To find the amount of money that the client will receive, all you have to do is subtract the amount that John receives.
To do this, you multiply 2.5% or 0.025 by 346,000.
0.025*346,000=8650. This means that John receives $8650 for helping this client sell their house.
346000-8650=337,350.
This means that the client receives $337,350 from the sale of their $346,000 home.
B. $337,350
