Abril earned a total of $60 mowing lawns around her neighborhood. she charges $8 an hour and received $20 in tips. use the equation 8h+20=60 to determine h, the number of hours she spent mowing lawns

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
