Question

How do you solve You earn 15n 15n dollars for mowing n lawns. How much do you earn for mowing one lawn? Seven lawns?

Answer 1

$15 for a lawn, $105 for seven lawns.

Explanation:

The question is about the direct ratio problem. Logically, you will earn more if you mow more lawn.

The scheme for this ratio is given below:

15 n_________n lawns

x_________ 1 lawn

`x=(15n*1)/(n) = 15`

You will earn 15 dollars for mowing a lawn

When you mow 7 lawns, the scheme will be in this manner:

15 n__________n lawns

x__________7 lawns

`x=(15n*7)/(n)=105`

You will earn 105 dollars
