Sandi works for elizabeth arden cosmetics and earns $500 per week salary plus 4% commission on sales over $2,000. if sandi sold $2,733 last week, what was her total compensation?

With the total sales of $2,733, the sales over $2,000 is $733. The commission she will receive is equal to the product of $733 and the decimal equivalent of the commission. That is,
                             commission = (0.04)($733)
                              commission = $29.32
The total compensation she will receive is the summation of the commission and weekly salary.
                       total compensation = $29.32 + $500 
                       total compensation = $529.32

This week, Sandi will receive a total compensation of $529.32.
