Question

Naomi has earned $54 mowing lawns the past two days.She worked 2 1/2 hrs yesterday and 4 1/4 hours today. If Naomi is paid the same amount for every hour she works, how many does she earn per hour to mow lawns

Answer 1

$8/hr

Explanation:

We're to find the hourly mowing rate, r.

Write and solve an equation in r:

2.5r + 4.25r = $54 total.

$54

Then 6.75r = $54, and r = --------- = 8.

6.75

Naomi earns $8 per hour for her lawn mowing.

Answer 2

Add up the hours (2.5 + 4.25 = 6.75)

$54 divided by the hours 6.75 = $8 per hour

Naomi is paid $8 per hour
