You are buying potato chips at the grocery store. You have a manufacturers coupon for a $1.00 off and the store is offering 20% off if you buy 2 bags. You decide to buy 2 bags of potato chips. How do you compute your final cost? A. Subtract $1.00 off each bag and then multiply by .20 B. Multiply each bag by .20, subtract $1.00 off of each bag, and then add them together. C. Add the two bags together, multiply by .80, and then subtract $1.00. D. Subtract $1.00 from the first bag, then add them together, and then multiply by .80.
The correct option is: C. Add the two bags together, multiply by .80, and then subtract $1.00.
First you need to add the prices of two bags for getting the total sales price.
Now, the store is offering 20% off, that means you need to pay 80% of the total sales price. For finding the amount, we need to multiply the total sales price by 0.80
Then, you have a manufacturers coupon for a $1.00 off. So, for fining the final price, you need to subtract that $1.00 from the last result.
Thus, the correct option will be......
C. Add the two bags together, multiply by .80, and then subtract $1.00.

Jasmine wants to use her savings of $1,128 to buy video games and music CDs. The total price of the music CDs she bought was $72. The video games cost $43 each. What is the maximum number of video games that Jasmine can buy with her savings? 24 25 26 27
Because she bought a CD on her savings, we must deduce the cost of the CD from her 1,128 savings
1128 - 72=1056
Then just divide the difference to how much each videogame cost
1056 / 43 = 24
So the answer is she can buy 24 videogames.
Distribution 4, mean is 20 and standard deviation is 3.2
The standard deviation tells us on average how far each of our data values is from the mean. A standard deviation that is larger than the others will mean a distribution that is more spread out than the others; 3.2 is the largest standard deviation, so Distribution 4 has the greatest spread.
If the equilibrium interest rate in the money market is 5%, then at an interest rate of 2% sellers of interest-bearing financial assets greater than interest rates to find willing buyers.
The sum of the angle measures of any triangle is 180 degrees. Suppose that one angle in a triangle has a degree measure of 7x+3 and another has a degree measure of 3x-6 . Write an expression for the degree measure of the third angle in the triangle.
180 = 7x+3 + 3x-6 + c
c = 180 - (7x+3 + 3x-6)
c = 180 - (10x - 3)
c = 177 - 10x
Hope this answers the question. Have a nice day.
To see which is better: divide $3.29 by 6 and then divide $4.15 by 8 and see which has the lowest answer.
The first option rounds off to $0.55 for one bagel. The second option rounds off to $0.52 for one bagel.
The second option is the best.
The soccer team voted on what they wanted to eat. there are 20 members on the team. six members voted for pizza, 10 voted for chicken, and the rest voted for hot dogs. which ratio represents the number of votes for hot dogs to chicken
Since there are 20 members in the soccer team. Then six members voted to eat pizza and 10 member voted to eat chicken and the rest is hotdog
Member voted for hotdog = 20 – 10 – 6 = 4
Ratio for hotdog to chicken is 10 : 4 or 5:2
The measured weights of 1,000 men in a certain village follow a normal distribution with a mean of 150 pounds and a standard deviation of 15 pounds. Which sentence most closely summarizes the data? About 160 people weigh more than 165 pounds. About 320 people weigh more than 165 pounds. About 320 people weigh less than 165 pounds. About 640 people weigh less than 165 pounds.
z1 = (165 - 150)/15 = +1
z2 = (135 - 150)/15 = - 1
According to the Empirical Rule 68-95-99.7
Mean +/- 1SD covers 68% of the values
100% - 68% = 32%
The remaining 32% is equally distributed below z = - 1 and z = +1
32%/2 = 16%
a) Number of men weighing more than 165 pounds = 16% of 1000 = 160
b) Number of men weighing less than 135 pounds = 16% of 1000 = 160
If ST = 21, SP = 3b – 11, and PT = b + 4, the value of b would be 14.
I hope my answer has come to your help. God bless and have a nice day ahead!
A sports memorabilia store makes $6 profit on each football it sells and $5.50 profit on each baseball it sells. In a typical month, it sells between 35 and 45 footballs and between 40 and 55 baseballs. The store has no more than 80 footballs and baseballs in stock during the month. What is the maximum profit the store can make from selling footballs and baseballs in a month?
Because for so solving the additive inverse of 9xy² + 6x²y - 5x³
-1(9xy² + 6x²y - 5x³) then it will turn to this ⇒ (-1)(9xy²) + (-1)(6x²y) + (-1)(-5x³)
-9xy² - 6x²y + 5x³ is the additive inverse of the given polynomial.
$850 x 7% = $59.50 (tax amount)
850 x (1+ 0.07) = $909.50
A department store has a discount on shoes based on a percentage of the price suppose one pair of shoes is marked down from $70 to $49 what is the price for a $100 pair of shoes after the discount is applied
$70 - $49 = 21
Now we find out what percent $21 is of $70.
21/70 × 100 = 30%.
That means the discount is 30%!
Now we must find 30% of $100, which is $30.
Then we subtract $30 from $100.
$100 - $30 = 70$
The first option has a price of $0.99 for one paper towel, and the second option has a price of $0.97 for one paper towel.
The second option is the better buy.
Sophia is saving money for a new bicycle. The bicycle will cost at least $623. Sophia makes $8.22 per hour. Which inequality could be used find the number of hours Sophia needs to work to make enough money to buy a new bicycle? $8.22h > $623 $8.22h ≤ $623 $8.22h ≥ $623 $8.22h < $623
We are given that Sophia is saving money for a new bicycle.
The bicycle will cost atleast $623.
Sophia makes $8.22 per hour.
We have to find the inequality that could be used to find the number of hours Sophia needs to work to make enough money to buy a new bicycle.
Let Sophia works h hours to make enough money to buy a new bicycle.
Sophia makes money per hour =$8.22
Total money made by Sophia in h hours =
According to question
Hence, option C is true.
Marcus finds that (3x^2-2y^2+5x)+(4x^2+12y-7x)= 7x^2-10y^2-2x What error did Marcus make? A: He combined the terms 5x and –7x incorrectly. B: He combined the terms 3x^2 and 4x^2 incorrectly. C: He combined the terms –2y^2 and 12y^2 incorrectly. D: He subtracted the polynomials instead of adding.
Combine like terms
the answer is the option C
He combined the terms and incorrectly
Katie ordered candles that cost $3 each from a website. She was charged a flat shipping fee of $6 and no sales tax. If she spent a total of $54, which equation can be used to find c, the number of candles she ordered? 3c = 54 6c = 54 3c + 6 = 54 3c – 6 = 54
Total return, when measuring performance, is the actual rate of return of aninvestment or a pool of investments over a given evaluation period. Total returnincludes interest, capital gains, dividends and distributions realized over a given period of time.
So the total return = (1000*2) + (1000/2) = $2500
60 minutes= 3600 seconds
3600 seconds *7 lego sets= 25200
