Answer:
$497.80
Step-by-step explanation:
First, you want to find half of 10.48. This should be 5.24.
So, add 10.48 and 5.24. This gives you 15.72.
Now, you want to multiply that by 5, since 5 hours were overtime.
This gives you 78.60.
Lastly, you want to multiply 10.48 by 40.
This gives you 419.20
Now, add 78.60 and 419.20 together, giving you your answer of $497.80
