Answer:
Step-by-step explanation:
Charlotte's revenue earned : R = 12.50h.....where R = revenue earned and h represents hrs worked
=======================
break even point :
12.50h = 45 + 2.50h
12.50h - 2.50h = 45
10h = 45
h = 45/10
h = 4.5 <== she would have to work 4.5 hrs to break even
========================
revenue - expenses = profit / loss
for 5 hrs...h = 5 for 3.5 hrs
12.50(5) - (45 + 2.5(5)) = 12.50(3.5) - (45 + 2.5(3.5)) =
62.5 - (45 + 12.5) = 43.75 - (45 + 8.75) =
62.5 - 57.5 = $ 5 profit 43.75 - 53.75 = -10....$ 10 loss
for 4 hrs for 7 hrs
12.50(4) - (45 + 2.50(4)) = 12.50(7) - (45 + 2.50(7)) =
50 - (45 + 10) = 87.5 - (45 + 17.5) =
50 - 55 = - 5.....$ 5 loss 87.5 - 62.5 = $ 25 profit
==================================
12.50h - (45 + 2.50h) = 50
12.50h - 45 - 2.50h = 50
10h - 45 = 50
10h = 50 + 45
10h = 95
h = 95/10
h = 9.5 <=== she would have to work 9.5 hrs to make a $ 50 profit
The two numbers are <u>19 and 52.</u>
<h3>
EXPLANATION</h3>
19 x 3 = 57, 57 - 5 = 52, 52 - 19 = 33.
