Question

A pet store sells dog food in a 3-pound bag for $12.00 and a 5-pound bag for $14.25. Which bag of dog food is the better buy? Explain

Answer 1

Answer:

3-pound bag=$12.00

5-pound bag=$14.25

3-pound bag is $12.00

∴1-pound bag=$12.00÷3

=$4.00

Here, 1-pound costs $4.00.

5-pound bag=$14.25

∴1-pound bag=$14.25÷5

=$2.85

Here, 1-pound costs $2.85.

Hence, buying 5-pound bag for $14.25 is the better buy.
