Question

Mark earns $135 for selling a $1,500 refrigerator. Which sale listed has the same commission rate? A) $36 commission on a $400 dryer sale B) $40 commission on a $500 dryer sale C) $210 commission on a $1,400 oven sale D) $30 commission on a $600 freezer sale

Answer 1

So the percentage Mark makes comparative to the price of the refrigerator sold is
`(135)/(1500)=0.09=` 9%. If we take 9% of the given sale prices:
A:
`0.09*400=36`
B:
`0.09*500=45`
C:
`0.09*1400=126`
D:
`0.09*600=54`

So (A) has the same commission rate.
