Over the last three years, Salesperson A has earned twice as much as Salesperson B, who in turn has averaged 50% more than Salesperson C. The three combined to make $220,000 over the three years. How much did Salesperson B earn on average in any year?
Answer provided by our tutors
Let
x = the amount salesperson C earned on average
x + 0.50x = 1.50x = the amount salesperson B earned on average
2*1.50x = 3x = the amount salesperson A earned on average
The three combined to make $220,000 means:
x + 1.50x + 3x = 220,000

x = $40,000
1.50x = 1.50*40,000 = $60,000
Salesperson B earned on average $60,000 for 3 years.
