Question

Tito Sanchez receives a weekly salary of $400 at Anderson Appliances. He also receives a 6% commission on the total dollar amount of all sales he makes. What must his total sales be in a week if he is to make a total of $790?

A.$1424

B.$2340

C.$6500

Answer 1

Let x = total dollar amount of sales

 

0.06x + 400 = 790

 

0.06x = 390

 

x = 390/0.06 = $6500
