Question

ezra is making a tray of macaroni and cheese for dinner. he melts 18 ounces of cheddar cheese in a pot. he decides to add cream cheese to make it really creamy. ezra plans to add less cream cheese than cheddar cheese. let c represent the amount of cream cheese, in ounces, that ezra might add. which inequality models the story? c > 18 c ≥ 18 c < 18 c ≤ 18 graph the inequality that models the story. to draw a ray, plot an endpoint and select an arrow. select an endpoint to change it from closed to open. select the middle of the ray to delete it. 10 11 12 13 14 15 16 17 18 19 20

Explanation:

Step1: Analyze the condition

Ezra adds less cream - cheese than cheddar cheese. Cheddar cheese is 18 ounces and $c$ is the amount of cream cheese.

Step2: Write the inequality

Since $c$ (amount of cream cheese) is less than 18 (amount of cheddar cheese), the inequality is $c < 18$.

Answer:

The inequality is $c < 18$. To graph it, plot an open - circle at 18 on the number line (because 18 is not included in the solution set, as it's $c < 18$ not $c\leq18$) and draw a ray to the left of 18.
