Answer:
$44
Step-by-step explanation:
First, find how much he was making originally:
Multiply the number of hours he worked by the amount he got per hour:
20(8)
= 160
Then, find how much he gets now:
24(8.50)
= 204
To find his total weekly pay increase, find the difference between them:
204 - 160
= 44
So, his total weekly pay increase is $44
