Step-by-step explanation:

To be able to solve this exercise we must begin by analyzing the information we have:

We know that Tyler's brother earns a 2.5% commission on what he sells.

We know he sold $ 900.

Now we just have to find out what that percentage was.

To do this we must multiply the percentage by the total, and divide it by 100:

(2,5,900): 100

2250: 100 = 22.50

This way we verify that the correct answer is $ 22.50.
