Question

Painter A charges 372 plus 12 per hour and painter B charges 280 plus 15 per hour in how many hours will they cost the same

Answer 1

Painter A 372+12h

Painter B 280+15h

372+12h=280+15h

subtract 12h from each side

372 = 280 + 3h

subtract 280 from each side

92 = 3h

divide each side by 3

30 2/3 =h

the cost the same at 30 2/3 hours
