Question

Leslie can buy her dog's food at Petco for $25 and receive 9 packs with four cans in each. Leslie can buy the same food at Petsmart for the same price with 7 packs of six cans in each. Which store should Leslie buy her dog food from?

Answer 1

Leslie should buy her dog food from Petsmart because the price per can is cheaper

Explanation:

Step one;

given data

At Petco, we are told that she receives 9 packs with four cans each for $25

Hence Petco gives a total of 9*4= 36cans

the cost of each can will be 25/36

=$0.69 per can

Step two:

At Petsmart, we are told that she receives 7 packs with six cans each for $25

Hence Petsmart gives a total of 7*6= 42cans

the cost of each can will be 25/42

=$0.59 per can

Leslie should buy her dog food from Petsmart because the price per can is cheaper
