Which would you use to determine how much money you have left over to save each month?

I would use a bank. :) Please mark as brainlest.

Step-by-step explanation:

I would use a bank because it tracks what you spent your money on, it tells you how much you spent, and it tells you how much you have.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

alright well the answers to your question is
