Answer

You have up to $130 left to spend each month.

Work Step by Step

The amount of money that you spend and save should be less than or equal to the amount of money that you earn. The amount of money that you spend/save each month is the sum of the club fee, your monthly savings, and your miscellaneous spending. Let m be the amount you have left to spend on miscellaneous things so 20+100+m≤250. Solve for m: 20+100+m≤250⟶ combine like terms 120+m≤250⟶ subtract 120 from each side m≤130 You can spend at most $130.
