Question 998984

A plumber makes $4.50 per hour moth than his apprentice. During an 8-hour day their earnings total $284. How much does each make per hour?
<pre>Let apprentice's hourly wage be A
Then plumber's is: A + 4.5
We then get: 8A + 8(A + 4.5) = 284
8A + 8A + 36 = 284
16A + 36 = 284
16A = 248
A, or apprentice's per-hour wage = {{{248/16}}}, or {{{highlight_green("$"15.50)}}}
You should be able to find the plumber's.
