Answer:
7.25 h = Â $36.25 Â is the required expression.
Cat worked 5 hours for the customer as babysitter.
Step-by-step explanation:
The hourly rate paid to cat for babysitting job = Â $7.25
Let us assume the number of hours cat worked = h hours
⇒The total amount paid for m working hours to Cat
= h x ( Cost of  working per hour)  = h  x $7.25
= 7.25 h
Also, the amount paid to Cat after h hours  = $36.25
According to question:
7.25 h = Â $36.25
or, h  = 36.25 / 7.25 = 5
⇒ h  = 5
Hence, Cat worked 5 hours for the customer as babysitter .
