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 $\frac{250*5}{100} = \frac{25*5}{10} = \frac{25}{2} =12.5$

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


 
 $\frac{250*8}{100} = \frac{25*8}{10} = \frac{25*4}{5} =20$

for each suit, and 60 in total.

his total comission was 125+60=185 dollars.
