as a real estate salesperson, you earn a small salary, plus a percentage of the selling price of each house you sell. if your salarly is $100 a week, plus 3.5% of the selling price of each house sold, what must your total annual home sales be for you to gross 30,000 in 1 year? assume that you work 50 weeks per year.

first step)

it is $ 100 * 3,5 % = 3,5 $, then 100 + 3,5 = % 103,5 per week

total earnings per year

30000 * 3,5 % = 31050

second step)

Now you must establish the following relation to determine the numbers of houses that you must sell on a week to obtain $ 31 050 in a year

1 house * $ 31050: $ 103 / week * 50 week = 6 house / week

now, to know the quantity of houses in 50 weeks, it is 6 houses * 50 weeks = 300 houses / 50 weeks, you must sell 300 houses in 50 weeks to earn $ 31050
