Jahla works at a book store. She makes a wage of $10 per hour and warns a 10% commission on her total sales. If she receives a paycheck of $500 and sold $3.500 worth of books , how many hours did she work?

Answer:

First we know he received a commission of 10% on all worth he sold  given by 10% of 3500 =10%*35000   =10/100*3500=350

Then the total earnings are 500 thus money per hour is

total earned - commission    =500-350=150

And this money was 10% of hours worked so we now ask ourselves  if 10% was 150 what about 100%

10%=150

100%  × ? then we cross- multiply

(100%*150)/10%  =  1500
