Problema Solution
a plumber finished three jobs on tuesday. the first two only cost the owner $45 trip fee because they took very little time to complete. for the third job, the plumber charged the trip fee plus 6 times his hourly rate. if the plumber received a total of $303 for the day, what is the hourly rate?
Answer provided by our tutors
Trip fee= $45
Total earned in trip fee = number of works * trip fee = 45 * 3 = 135
Amount earned by hourly rate = 303 - 135 = 168
He charged 6 times his hourly rate
=> let his hourly rate = x
=> he charged 6x
=> 6x = 168 => x = 28
