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.

= 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.

= 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.

= 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 .
