Matt starts a new job, with the goal of doubling his old average commission of $400. He takes a 10% commission, making commissions of $100.00, $200.00, $250.00, $700.00, and $1,000 on his first 5 sales. If Matt made two sales on the last day of the week, how much would Matt have had to sell in order to meet his goal?

Here is one way.....

he wants to double his commission from $400 to $800

100+200+250+700+1000+x+y
---------------------------------------- = 800
7

i.e 2250+x+y = 5600
x+y = 3350

Now he has to sell
10/100 * z = 3350
z= 33500

He has to sell 33500 in order to double his average.

If useful please click on thanks....:)
