Answer:
$81
Explanation:
First, find out how much he charges for raking 1 bag of leaves. The following equation can solve for the amount charged per bag.
[b = amount charged per bag]
15/5 = b
15/5 = 3
3 = b
This means he charges $3 for one bag.
Martin rakes 27 bags, so multiply 3 by 27 to find the total amount of money he earned
27(3) = 81
So, Martin earned $81 for raking 27 bags of leaves
