#1: Defines appropriate variable
#2: Accurately writes inequality
#3: Accurately solves and interprets inequality

Question 2

2.

Translate--Do not solve. Just write an inequality to model the situation.

Alberto wants to get Xbox Game Pass so he can play different games. He has $140 left over from the holidays. First he will spend $60 on a new controller, then he wants to use the rest of his money for the subscription fee.
Game Pass is $9.99 per month.
At most, how many months can he pay for with his current budget? Use m to represent the months of Game Pass.
