Inequality Word Problems
Solving inequality word problems follows similar rules as for equation word problems.

Example: Harry wants to make over $ 500 per week selling cars. He receives $100 in salary each week and gets a commission of $50 a car.  How many cars does he have to sell to receive more than $500 a week?


1.Let x equal the unknown.       x = the number of cars to sell.
2. With other unknowns make them into a relationship with the primary (x).
           let x(50) = the amount of commission Harry will receive.
3. Make 2 expressions be > or < to each other. 
            commission + salary > total    50x + 100 > 500

4. Solve
        Note: Whenever you multiply or divide both sides of an inequality by a
        negative number the sign of the inequality changes direction.
