Question

How many cans of food can I buy with $50​

Answer 1

It depends on how much the cans of food cost

Answer 2

That depends on how much each of them are. To find it, divide 50 by the cost
For example you have $50. Each can costs $0.50. Divide 50 by .5
50/.5=100
So you can buy 100 cans if they costs $0.50 each
