A plumber makes $4.50 per hour more than his apprentice. During an 8-hour day, their combined earnings total $372. How much does each make per hour? (hint: if you decide to use cents instead of dollars,then use 450 cents per hour and 37200 cents total earnings)

  • Math - ,

    Let x = plumber's wage, then x-4.5 = apprentice's.

    8(x + x - 4.5) = 372

    Solve for x, then x-4.5.
