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?

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

Step-by-step 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
