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/Roll = Sheets!
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.
c. costs $
per sheet (rounded to three decimal places...this is necessary because two decimal places is too few to show a difference compared to the WalMart package).
Hint: This question is the reverse of part b which asked for sheets per dollar. Now you need dollars per sheet. You need the same pieces of information connected in a different way.
