Mae ling earns a weekly salary of $370 plus a 7.0% commission on sales at a gift shop. how much would she make in a work week if she sold $4500 worth of merchandise?

4500*.07 is 315 315+370 is 685 so $685.00

First, let's turn 7% into a decimal by moving the decimal point two places to the left.

7% = .07

Now, multiply it by the amount of sales, because commission is money based on, well, sales.

4500 * .07 = 315

Add the commision to the sales.

4500 + 315 = 4815

Add the weekly salary to the current price.

370 + 4815 = 5185

With commission and her initial weekly salary, Mae Ling earned $5185.
