Tyler brother earns a commission .he makes 2.5 of the amount he sells. last week he sold 900 worth of shoes. how much is the commission

Commission = $22.50

Step-by-step explanation:

Given,

The amount of sales = $900

The commission = 2.5%

We will use the unitary method to determine the commission,

When the selling price is 100, the commission is        $2.50

When the selling price is 1, the commission is             $2.50/100

When the selling price is 900, the commission is       $(2.50/100) x 900

                                                                                      =$2.50 x 9 = $22.50

Therefore, Tyler makes $22.50 worth commission after selling $900 worth of shoes.
