Question
A particular brand of toilet paper is offered at two stores in different kinds of packaging. To practice using rates, for each package determine both the number of sheets per dollar and the cost in dollars per sheet. Then determine which package is the better buy.
Sams Club sells a 36-pack of the toilet paper with 248 sheets per roll for $26.99
Walmart sells the toilet paper for $5.99 in an 8-pack with 350 sheets per roll
The Sam's Club package:
a. contains sheets of toilet paper altogether.
Hint: This is a perfect place for dimensional analysis. Rolls x
= Sheets!
Hint: This is a perfect place for dimensional analysis. Rolls x
| Sheets |
| Roll |
b. has sheets per dollar (rounded to the nearest whole sheet)
Hint: Remember that "per" indicates division. You know how many sheets are in the package. You also know how much the package costs. Use those two pieces of information together to answer this question.
