Ms. Donaldson earns $18.80 per hour for the first 40 hours she works in a week. She earns 1 1/2 times that amount per hour for each hour beyond 40 hours in a week. Last week Ms. Donaldson worked 45.5 hours. How much money did she earn? Explain your answer and show your work

Answers

You take $18.80 divide by 2 =$9.40 then $18.80+$9.40=$28.20
$28.20 x's 5.5=$$155.10
$18.80 x's 40=$752.00
then add 752.00+155.10=$907.10
so each hour i 18.8
18.8 times 40=752
18.8 times 5.5 times 1.5=155.1
752+155.1=907.1

Substitute for C = 20
F = 9*20 / 5 + 32
F = 180 / 5 + 32
F = 36 + 32
F = 68
