Commission Question.

Question

Marie sells outdoor grills. She knows she earns 10% commission on the first $10,000 and 12% on the next $15,000. She does not remember the rate on the sales of more than $25,000. Her total sales of the month are $30,000, and her total commission is $3,550. What is her rate of commission of the sales over $25,000

Answer 1

10,000(.1) + 15,000(.12) + 5000(c) = 3550

 

The 5000 is the difference between 25000 and 30000.

 

1000 + 1800 + 5000c = 3550

5000c = 750

c = .15

 

Her commission above $25,000 is 15%.
