Answer:
The total commission be $1470 .
Step-by-step explanation:
As given
Cody Summer sells tires for tractor trailers.
Last month he sold $18,000 worth of tires.
Divide this $18000 in three parts = $6000 + $6000 + $6000
As given
He earns 4.5% commission on the first $6,000 in sales.
4.5% is written in the decimal form.
[tex]= \frac{4.5}{100}[/tex]
= 0.045
Cody Summer earns commission on first $6,000 in sales = 0.045 × 6000
=$ 270
8% commission on the next $6,000 .
8% is written in the decimal form.
[tex]= \frac{8}{100}[/tex]
= 0.08
Cody Summer earns commission on second $6,000 in sales = 0.08 × 6000
=$ 480
12% commission on sales over $12,000.
As the total Cody Summer sold $18,000 worth of tires.
Thus
worth of tires sales over $12,000 = $18000 - $12000
=$6000
12% is written in the decimal form.
[tex]= \frac{12}{100}[/tex]
= 0.12
Commission on sales over $12,000 = 0.12 × 6000
=$720
Total commission = Cody Summer earns commission on first $6,000 in sales + Cody Summer earns commission on second $6,000 in sales + Commission on sales over $12,000
Put the value in the above
= $ 270 + $ 480 + $720
= $1470
Therefore the total commission be $1470 .
