Answer:
There are 40 problems on the test
Step-by-step explanation:
Let p = the number of problems on the test
The number of problems on the test times the percent correct is the number correct
p * 85% = 34
p * .85 = 34
Divide each side by .85
p * .85/.85 = 34/.85
p = 40

In order to find out what deal is better:
- We have to find the unit rate for each deal
- Total amount of paper towels ÷ The price
So it would be....
- 18 ÷ 14 = 1.285714
- 12 ÷ 10 = 1.2
Short Answer:
The better deal is 10 rolls of paper towels for $12.
Long Answer:
I wanted to find out the price per roll of paper towel for each deal so I created a unit rate problem which is the numerator divided by the denominator. From there, I was able to get my answers, compare which one was less than the other, and select the best deal.
