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.
