Question

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. What is the greatest number of cups of yogurt Monica can buy? Use the inequality 1.20x + 2.5 ≤ 20 to solve the problem

Answer 1

Subtract 2.5 from both sides
1.20x <20-2.5
1.20 x<17.5
Divide both sides by 1.20
X< 14.58
At the most she can buy 14 cups

Answer 2

The greatest amount she can buy is 14 yogurt cups
