Answer:
$37.70
Step-by-step explanation:
To find the answer:
8.90 is the hourly pay for mowing. Since Michael has only done one hour, 8.90 x 1 + 8.90. Michael has earned $8.90 from mowing.
The hourly pay for babysitting is $7.20.
7.20 x 4 = 28.8
Now add the two numbers together
28.8 + 8.9 = $37.70
The answer is $37.70
