kedar earns a monthly salary of $2,200 plus a 3.75% commission on the amount of his sales at a mens clothing store. what would he earn this month if he sold $4,500 in clothing? round off to the nearest cent

Answers

$2200 + 3.75% of $4500 would be 2200 + 0.0375 x 4500 or $2200 + $168.75

2200 + 168.75 = $2368.75

Answer:

2368.75 total cost

Step-by-step explanation:

3.75% divided by 100 = 0.0375.

Then 4500 X 0.0375= $168.75.

2,200 + 168.75 = 2,368.75.

= 2,368.75 total cost.
