To answer this question, we need to use the concept of unit rate. In this case, to find the payment per hour of Job number 1, we can proceed as follows:
[tex]\frac{52.50\text{dollars}}{7\text{hours}}=\frac{7.5d}{h}[/tex]Therefore, Job number one pays $7.50 per hour (to the nearest cent).
(We divided the total amount of money by the total amount of time to find the number of dollars per hour.)
