Problema Solution
For a recent job, a plumber $28 per hour and his apprentice earned $15 per hour. The plumber worked 3 hours more than the apprentice. If they worked together they were paid $213, how much did each earn.
Answer provided by our tutors
Let 'p' and 'a' stand for the amount of time that the plumber and apprentice each worked.
28p+15a=213
p=a+3
Using Algebrator to solve for 'p' and 'a', we get:
a=3
p=6
Amount that each earned:
plumber: 28(6)= $168
apprentice: 15(3)= $45
