Question

Juan Ramirez sells suits in a major department store on weekends. He earns a commission of 5 percent on the first ten suits, and if he sells more than ten, he earns an additional 3 percent on the additional suits. Last weekend Juan sold thirteen $250 suits. What was his commission?

Answer 1

so, the first 10 suits came with a commission of 5%, so for each suit it was:

250*5%

this is
`(250*5)/(100) = (25*5)/(10) = (25)/(2) =12.5`

but this counts for 10 suits, so together his commssion was 10*12.5=125 dollars

and the "extra" 3 suits came with a comittion of 5+3 percent, so 8 percent, which is




`(250*8)/(100) = (25*8)/(10) = (25*4)/(5) =20`

for each suit, and 60 in total.

his total comission was 125+60=185 dollars.
