Ok, so now I have a new issue I didn't think of before this.
lets say the moneyMaker = 16,000 and the carPrice is 14,500
Yes it goes to zero which is what I asked for but I see that what I really need now is only take the amount needed. The monies is being distributed to different places of the players choosing. But the chance that the money made being the exact amount need for the car is very slim. It will be like 500,
250, 50, 1500, increments. So basically you save up for you items you want. But by adding it to the amount of the car until it's 0. Than you get the car.
