Explanation:
A sales quota is the minimum volume a salesperson is expected to move to earn commissions.
Mark's quota is $2750
In the week, mark sold $29,000, but $1,800 was returned. The net sales were: $29,000 - $ 1,800 = $27,200
Mark is a 10% commission. The commissions will be 10% of net sales
=10/100 x $27,200
=0.1 x $27,200

gross pay will be weekly earnings plus commissions
=$400 +$2,720
=$3,120
