Question

marco needs to buy some dog food. at the nearest store, 5 bags of dog food cost $12.50. how much would marco spend on 3 bags of dog food

Answer 1

Answer: 7.5 bags

Explanation:

$12.50 divided by 5 bags= $2.5 per bag

$2.5*3 bags= $7.5

Answer 2

7.5

Explanation:

Since we are given the price for 5 bags of dog food, we have to find the unit rate. Now to do that we divide the price by the amount.

12.50/5= 2.50

now since we have the unit rate, we take that and multiply the price of one by 3 to find the price of 3

2.50x3=7.50

Hope this helps!
