frank commons earns an 8% commission as a real estate agent how much will he earn on the sale 124,000 house?

All we need to do is to find out how much is 8% from $124 000:

x = 8% from $124000 (where x is Frank's commission)

x = 8/100 * 124000

x = 8/1 * 1240 (after simplifying both numbers)

x = 8 * 1240

x = 9920

Answer: Frank will earn $9920 on the sale of $124 000 house.
