Question

PLUMBING Al Plumbing Service charges $35 per

hour plus a $25 travel charge for a service call. Good
Guys Plumbing Repair charges $40 per hour for a
service call with no travel charge. How long must a
service call be for the two companies to charge the
same amount?​

Answer 1

A service call at 5 hours would cost the same amount at each company.

Explanation:

At one hour Al Plumbing charges $60 ($35+$25 travel charge) and Guys Plumbing charges $40. From there I added $35 to Al's total and $40 to Guy's until they each reached $200 at 5 hours.
