Annette earns a salary of $152 per week, plus a commission of $12 for each painting she sells. How many paintings must she sell in a week to earn $440?

May 18th, 2015

Basic salary = $152

Total earning = $440

Total commission = $440 - $152 =$ 288

Commission per painting sold $12

So number of paintings = 288/12 = 24.
