You can put this solution on YOUR website!
Let +x+ = the hourly rate of the apprentice in dollars/hr
+x+%2B+25+ = the hourly rate of the plumber in dollars/hr
given:
+40x+%2B+40%2A%28+x+%2B+25+%29+=+2600+
+40%2A%28+x+%2B+x+%2B+25+%29+=+2600+
+2x+%2B+25+=+65+
+2x+=+40+
+x+=+20+
+x+%2B+25+=+45+
The hourly rate of the apprentice is $20/hr
The hourly rate of the plumber is $45/hr
