Answer:

$8/hr

Step-by-step 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.
