A used furniture store buys old mattresses for $50 and sell them for $200.
Write an inequality representing all the possible combinations of mattress
purchases and sales that will result in a profit of less than $1500
~~~~~~~~~~~~~~~~~~~~~~~ 

Let x be the number of bought mattresses,
and let y be the number of sold mattresses.


Then the inequality for the profit is


    -50x + 200y < 1500 dollars.


Accompanied inequalities are  

    x >= 9,  y >= 0.

Solved.
