Three times the sum of half Carlita's age and 3 is at least 12. What values represent Carlita's possible age? Graph the solution.

Answer 1

Hi.

To solve this, we are going to need to start by using a letter to represent Carlita's age (we'll use "C") and then write an inequality:

3 (0.5C + 3) ≥ 12

1.5C + 9 ≥ 12

1.5C ≥ 3

C ≥ 2

I'll leave the graphing part to you! :)
