Owners of the 650 homes in a subdivision list their houses, on average, every six years. if a sales associate farms that neighborhood and lists 40% of the homes, how many homes can she expect to list this year

There are 650 homes.

Owners list their homes on the average, every six years.

Therefore average number of homes listed per year is

650/6 = 108.333 homes

If a sales associate lists 40% of the homes in a year, she can expect to list

40%*108.333 = 0.4*108.333 = 43.33

We cannot have fractional homes, so the sales associate lists 43 homes per year.

Answer: 43 homes
