Question

Nancy's sales last week were $170 less than three times Andrea's sales. Together they sold $940. Determine how much each person sold last week. (Do not include the $ sign in your answers.) (Don't use the, comma to indicate thousands.) Nancy's sales = Andrea's Sales =

Answer 1

Let n = Nancy's sales

a = Andrea's sales

n = 3a - 170

n + a = 940

3a - 170 + a = 940

4a = 1110

a = $277.50, n = $662.50
