Most real estate agents are paid on commissions and do not receive a salary.
The average commission for an agent is 3% of the sale price of the house. In
2017, Elena helped 4 different buyers find new homes. The sale prices of these
4 homes are given in the box to the right. If Elena made a 3% commission on
each house, how much did she make for the entire year? You may use a
calculator. (explain work)

Sale prices
$610,000
$825,000
$950,000
