Question 912677: Can you help me with the problem below:
A real estate salesperson usually works for a small salary plus a percentage of each house she sells. If her salary is $100 a week plus 3.5% of the price of each house sold, how many dollars' work of houses must she sell in order to clear $20,000 in one year? Assume she works 50 weeks per year.
Answer by mananth(16946)   (Show Source):
You can put this solution on YOUR website! Let the value of the houses she sells in a year be x
100 per week
50 weeks in a year
I = 5000+3.5% *x
I> 20,000
5000+3.5%x>20,000
multiply by 100
500000+3.5x > 2000000
3.5x >2000000-500000
3.5x >1500000
x>1500000/3.5
x>428,752
