# Answer

To solve this we need to create an equation:

First we have the comission of sales which is 30%: 0,3X where X is the weekly total sales amount.

And the 50$ weekly payment.

So to figure out the total weekly earning:Y , we need to add the sales commissions with the 50$ weekly payment:

**Y= 0,3X + 50**

And having the weekly sales X, we can easly calculate the total weekly earning.
