Writing an Inequality
Monica has $20. She needs to buy a gallon of milk that costs $2.50. She also wants to buy yogurt, which costs $1.20 a cup. Which inequality can you use to find the number of cups of yogurt Monica can buy?
1.20x + 2.5 Greater-than-or-equal-to 20
1.20x + 2.5 Less-than-or-equal-to 20
1.20x + 2.5 < 20
1.20x + 2.5 > 20

She can't spend more than $20, so the total cost must be less than or equal to 20:

1.20x + 2.5 ≤ 20.

Solving: 1.20x ≤ 17.5 → x ≤ 17.5/1.2 ≈ 14.58, so she can buy at most 14 whole cups.
