OK so every week she gets a **Basic** of $250, plus **Commision**.

Last week she made a **Grand Total** of $975.

So last week her **Commission** was **Grand Total** minus** Basic**

975 - 250 = 725

So her **Commision** was $725.

Her **Commisson** is 20% of what she sells.

So 725 is 20% of her sales total.

20% is a fifth.

So 725 is a fifth of her total.

So 725 X 5 = Sales Total

Sales Total = ?

Translate the problem into the commission. You know that

salary + commission = pay

250 + 20% of sales = 975

Since you are looking for sales, let that be x. 20% is 0.20. "Of" means times.

250 + 0.20x = 975

Then solve the equation to find sales.

250 + 0.20x = 975

-250 -250

0.20x = 725

Divide by 0.20

x = 3625

So she sold $3625 worth.

She got a basic salary of 250 dollars per week + 20% commission per week.

Since last week, her pay was 975 dollars

First, we must subtract basic salary from the total money earned which is 975-250= 725 dollars

Since she got 20% commission , let sales be x

0.2x=725

x= 3625 dollars
