For a recent job, a plumber earned $28/h, and the plumbers apprentice earned $15/h. The plumber worked 3 hours more than the apprentice. If together they were paid $213 , how much did each earn?
------------------------
Plumber DATA:
rate = 28/h ; time = x+3 hrs ; Pay = r*t = 28(x+3) 28x + 84
------
Apprentise DATA:
rate = 15/h ; time = x hrs ; Pay = r*t = 15x
0000000
Equation:
28x + 84 + 15x = 213
43x = 129
=======================
x = 3
---------------
Plumber pay = 28x+84 = 28*3+84 = 84+84 = 168
Apprentise pay = 15x = 15*3 = 45
=====================
