Question 34373: A bricklayer and an electrician together spend 90 hours working on a new house. If the bricklayer earns $12 per hour, the electrician earns $16 an hour, and the owner pays them a total of $1350 for their work, how many hours does each worker spend on the house?
Answer by hydromojo(20)   (Show Source):
You can put this solution on YOUR website! Suppose the bricklayer work for 'X' hrs, the electrician works for (90-X) hrs
their pay will be 12X & 16*(90-X)
They get a total of $1350 for their work.
So, 12X + 16*(90-X) = 1350
Solving for X, you get 22.5, and the eletrician works for 67.5hrs
