Question

You earn $80 for working 10 hours. How much do you earn for 2.5 hours? (RATIOS)

Answer 1

Money : Hours

$80 : 10

So let x be the money you earn for 2.5 hours.

x : 2.5

You just need to do this: 80/(10/2.5)

= 80/4

= 20

So you earn $20 for 2.5 hours.

Answer 2

$20

Explanation:

To solve this problem, you need to first find the amount earned per hour (x), then multiply that number by 2.5 hours.

x = 80/10

x = 8

8*2.5 = 20
