How do you figure this out? Keith plans to buy a car when he is 16. He currently has $3,000 saved up to buy the car. If his parents plan to give him $2,500 as a birthday gift when he turns 16, and Keith wants to spend at least $2,000 of it on his $15,000 car. What is the most amount of money he would need to save each month now (for the next two years) now that he is anticipating his birthday gift?
