Answer:
$346.65
Explanation:
If Marcus worked a total of 40 hours, and he earns 10$ an hour, his payment before deductions is 400$, as put in the "gross pay".
We need to sum all the deductions:
9.75 + 3.10 + 30 + 10.5 = 53.35
Now, to know Marcus net pay, we just need to subtract his gross pay from this total deduction:
400 - 53.35 = 346.65
So, his net payment is $346.65
