Question

Amy and Dex are going to a play. Dex wants to have at least $65 in his wallet. He currently has $10. How do you write and solve an inequality to find how much more cash Dex should put in his wallet?

Answer 1

Let's call the additional amount of money Dex needs in his wallet `d`. Also, the inequality we will write will contain the `>=` sign because Dex wants to have "at least". We can then write:

`$10 + d >= $65`
