Answer:
$485.05 per week of 43 hours labor
Explanation:
First of all, we already know that he works the first 40 hours, so:
$10.90*40= $436
Now it says the next three hours are 1.5* the original pay;
$10.90*1.5= $16.32 (x 3 because thats the extra hours)
$16.32*3 = $49.05
Now, we add the numbers:
$436+$49.05= $485.05
All done!
