Answer:
Step-by-step explanation:
Anna had less than 30 cookies to start with. Let’s assume that she had x cookies to begin with. After eating 12 cookies, she would have x - 12 cookies left.
We can write an inequality to represent the number of cookies Anna has left:
x−12<30
To solve for x, we can add 12 to both sides of the inequality:
x−12+12<30+12
Simplifying the inequality:
x<42
Therefore, Anna had less than 42 cookies to begin with and after eating 12 cookies, she would have x - 12 cookies left, where x is less than 42.
