Suppose you have $344.25 and you spend $6.75 per day on lunch.

Part 1: Write an equation to represent the amount of money you have after, d, days of buying your lunch. Let A = the amount of money left in your account after d days. Explain why your equation makes sense. (What do any numbers in your equation mean?)

Part 2: How many days does it take for you to have no money left for lunch? Explain how you calculated this.

Remember that you must show all work and fully explain your thinking on the problem.
