Answer:
$ 73.71/wk 
Explanation:
Number of working hours in a week = 15 hours 
Payment per hour = $ 8.95 
Total deductions on hourly payment = 
8.95x7.65%=0.685 
8.95x9.3%=0.832 
8.95x5.8%=0.519 
Total deduction = (0.685 + 0.832+ 0.519) = 2.036 
Net payment per hour after deductions = $ 8.95 - 2.036 
= $ 6.914 
Total weekly payment 
= Number of working hours in a week x Net payment per hour 
= 15 hours/wk x $ 6.914 
= $ 103.71/wk 
The discretionary income left after saving = $ 103.71/wk - $30.00/wk 
= $ 73.71/wk
