Answer:
She spent 5 hours mowing lawns.
Step-by-step explanation:
To solve, we will just use some algebra
8h + 20 = 60 | Subtract 20 from both sides
8h = 40 | Divide both sides by 8
h = 5
We can confirm this by plugging it back into the original formula.
8(5) + 20 = 60
40 + 20 = 60
60 = 60

Lol I just answered the same question minutes ago. Here is the answer I gave him/her.
Total Cost : 1800
12 dollars * 16 hours = 192 dollars earned
0.2 percent * 192 = 38.4 dollars saved
A.She earns 192 dollars every week
B. she will save 38.4 dollars * 7 weeks = 268.8 dollars in a week.
C. 7 days times 4.3 weeks = 30.1 days. 30.1 days * 38.4 = 1,155.84 dollars every month.
D. it will take her about 2 months to save the money. To be exact: 1.6 months.
Hope this helped!
