Lucy has $20 to spend at the store. She is already buying a shirt that costs $8. Which inequality can be used to find how much money she has left to spend?

Answer 1

To find out how much money Lucy has left to spend after buying the shirt, you can start with the total amount of money she has, which is $20, and subtract the cost of the shirt, which is $8.

Let \( x \) be the amount of money Lucy has left after buying the shirt. The inequality can be expressed as:

\[ x \geq 20 - 8 \]

Simplifying the right side gives:

\[ x \geq 12 \]

This inequality tells us that after buying the shirt, Lucy has at least $12 left to spend.

So the inequality \( x \geq 12 \) can be used to find how much money she has left to spend.
