Question

Erica, a sales clerk in a sporting goods store, earns a base salary of $1,500 per month plus a commission of 5 percent on monthly sales over $500. If Erica received $1,700 for the month of July, how much were her monthly sales?

A: $3,200

B: $3,700

C: $4,000

D: $4,500

Answer 1

$1700 = 1500 + 0.05x
$200 = 0.05x
$4000 = x
$4000 + $500 = $4500 Sales in July (since she does not get commission on the first $500)
