The amount an appliance repairman charges for each job is represented by the function t = 50h + 35, where h represents the number of hours he spent on
the job and t represents the total amount he charges in dollars for the job. The
repairman plans to change the amount he charges for each job. The amount he
plans to charge is represented by the function t = 50h + 45. What will be the
effect of this change on the amount he charges for each job?
