Question

At a wholesale club, you can buy packages of 6 bottles of shampoo for $14.10. A drugstore is offering the same shampoo this week for $4.50 for 2 bottles. Which is the better buy? Show your work, or explain in words how you determined your answer.

Answer 1

At a wholesale club, the shampoo costs $2.35 each. At a drugstore, the shampoo costs $2.25 each. $14.10 divided by 6 is $2.35 and $4.50 divided by 2 is $2.25.

Answer 2

Find the unit rate to see what price is better.
14.10/6 = 2.35 each
4.50/2 = 2.25 each
The 2 pack at the drugstore is a better price because each bottle is 10cents cheaper than at the wholesale club.
