Tony makes an hourly salary of 15.40 for 40 regular hours of work. for any time work beyond 40 hours, he is paid at a rate of time and a half per hour. last week, tony worked 46 hours. find each of the following for this period.

I have added a screenshot with the complete question.

Part (1):
We know that:For the first 40 hours, Tony is paid $11.5 per hour For additional hours,Tony is paid 1.5 * 11.5 = $17.25 for each hourLast week he worked 46 hours.Therefore:he got the normal payment of $11.5 for the first 40 hourshe got the special payment of $17.25 for the extra 6 hoursThis means that:Total amount he gained = 40(11.5) + 6(17.25) = $563.5This means that, before removing any taxes or insurances, Tony had a payment of $563.5

Part (2):
We are given that the social security tax is 6.2% of the amount he gained.
Therefore:
social security tax = 6.2% * 563.5
social security tax = 0.062 * 563.5
social security tax = $34.937

Part (3):
We are given that the medicare tax is 1.45% of the amount he gained.
Therefore:
medicare tax = 1.45% * 563.5
medicare tax = 0.0145 * 563.5
medicare tax = $8.17075

Part 4):
To get the amount that Tony has after all the taxes are paid, we will simply subtract the amount of taxes from what he originally gained as follows:final amount gained = 563.5 - (34.937+8.17075)final amount gained after taxes = $520.39225

Hope this helps :)
