Commission Sales
10% $0.00 - $10,000.00
5% $10,000.01 --->
He does not earn double commission.That is, if his sales are $12,000, he earns 10% on the first $10,000 and 5% on the remaining $2,000.
His largest paycheck of the year was $1,320. What were his sales for that pay period?  Choose the correct choice from the following choices.
A) A)13,000
B) B)13,200
C) C)16,400
D) D)15,800
E) E)19,600
His pay check was $1320.   Out of this, $160 was his fixed salary so the total commission he earned was $1320 - $160 = $1160   He earns 10% on the sales of first $10,000 which gives a commission of $1000.   He earns 5% on every subsequent dollar. Since he earns another $160, he must have had sales of another 160*(100/5)  1320 -  160=
