Rhono has a part-time job at the local supermarket working 3 hours after school each night and 5 hours on saturdays. His gross hourly pay is $8.75. Estimate and then calculate his next wages for the month, after 20% tax is deducted. Each month his expenses are: Entertainment $35.00, health and beauty $21.00, transport $18.00, clothing $24.00, hire purhases payments $15.75. Calculate the amount Rhono has left over at the end of each month, and how much he would have saved at the end of 12 months.

Respuesta :

Rhono apparently works 5*3+5 = 20 hours per week. His net pay for 4 weeks* is
.. 4*20*8.75*(1 -0.20) = $560

The listed expenses add to
.. 35 +21 +18 +24 +15.75 = 113.75

The amount left over at the end of each 4-week period is
.. $560 -113.75 = $446.25

If he saves the remainder, after 12 months, he will have saved
.. 12*$446.25 = $5,355.00

___
* There are 13 periods of 4 weeks in a year. If Rhono takes no vacation, his savings balance may be $560 more than the above amount, that is, $5,915.00.
