A plumber makes $4.50 per hour than his apprentice. During an 8-hour day their earnings total $284. How much does each make per hour?
-----------------------------------------------------------------
Let x and y be the earnings of a plumber and his apprentice per day (per 8-hour working day).
Then we have the system of two linear equation in two unknowns
x + y = 284,
x - y = 8*4.50 = 36.
Add both equations. You will get
2x = 284 + 36 = 320. Hence, x = = 160.
Then y = 284 - 160 = 124.
Thus the plumber makes = $20 per hour.
The apprentice makes = $15.50 per hour.

Let apprentice's hourly wage be A
Then plumber's is: A + 4.5
We then get: 8A + 8(A + 4.5) = 284
8A + 8A + 36 = 284
16A + 36 = 284
16A = 248
A, or apprentice's per-hour wage = , or
You should be able to find the plumber's.
