Answer:
b,d,e
Step-by-step explanation:
Rock the House
Cost = initial fee + hourly charge * hours
Cost = 500 + 50h
Elegant Homes
Cost = initial fee + hourly charge * hours
Cost = 0+ 75h
Cost = 75h
Set the costs equal
500+ 50h = 75h
Subtract 50 h from each side
500 = 25h
Divide by 25
500/25= 25h/25
25 =h
The costs are equal at 20 hours
If less than 20 hours it costs less at Elegant homes.
If more than 20 hours it costs less at Rock the house
