Liz earns a salary of $2,100 per month, plus a commission of 5% of her sales. She wants to earn at least $2,400 this month. Write an inequality to find amounts of sales that will meet her goal. Indentify what your variable represents.

Let x = the amount of sales for the month
Now commission for the month would be 5% of "x" or 0.05x

Adding the monthly salary plus the commission needs be greater than or equal to $2400.

So the inequality would be:  0.05x + 2100 ≥ 2400
