The amount a pool repairman charges for each job is
represented by the function
p= 65h + 45,
where h represents the number of hours he spent on
the job and p represents the total amount he charges
in dollars for the job. The repairman plans to change
the amount he charges for each job represented by
the function
p= 75h + 45.
What will be the effect of this change on the amount
he charges for each job?
