Answer:
Commission received by Edison =$15112
Step-by-step explanation:
It is given that,
Edison has a sales job and receives $45,448 as his annual pay, plus commission.
His company pays him a commission of 15% on his total sales.
He makes sales of $25,000 in the first 3 months,

Commission = (15 x 25,000 )/100 =$ 3750
<u>To find amount paid for 3 months </u>
Amount = 45,448/4 = $11362
he will be paid for those 3 months =11362 + 3750 = $15112

Answer:
"$/km"
Step-by-step explanation:
He wants to model "maintenance cost" with respect to "distance"
Normally,
maintenance cost would be in currency --- dollars, pounds etc.
distance would be in kilometers, miles, meters etc.
We need to find the ratio that has the COST on top and DISTANCE on bottom
Looking at the choices,
We can eliminate 1st and 3rd immediately as it doesn't have COST on top.
That leaves us with
$/km
and
km/$
$ is in fact currency and unit for cost and km is in fact unit for distance. We need the ratio that has $ on top and km on bottom, that's the 2nd option.
So, $/km is the appropriate unit.
