A salesperson earns ​$125 selling ​$2500 worth of television sets. What is the commission​ rate?

To find the commission rate, divide the commission earned ($125) by the total amount of sales made ($2500) and multiply by 100 to get a percentage:

Commission rate = (Commission earned / Total sales) x 100
= (125 / 2500) x 100
= 0.05 x 100
= 5

The commission rate is 5%.
