# 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?

Let's call the additional amount of money Dex needs in his wallet $d$. Also, the inequality we will write will contain the $\ge$ sign because Dex wants to have "at least". We can then write:
$10 + d >=$65
