Problema Solution

a realestate agent recieves monthly salary of $1500 plus 4% comission on every home sold. For what amount of monthly sales will the agent earn at least $5000

Answer provided by our tutors

Let monthly sales = $ x

Monthly salary = $ 1500

Commission = 4 % = $ x * 0.04 

Total amount = $ 5000 

therefore 

1500 + 0.04 x  = 5000 

or    0.04 x = 5000 - 1500 = 3500

or 0.04 x = 3500 

x = 3500 / 0.04 = 87500

Minimum sales should be = $ 87500 (answer)
