Give the step-by-step reasoning process and then the final answer. Randy has some money in his piggy bank. He spends 2 dollars every time he goes to the store. He makes 4 trips to the store every month. If he had $104 dollars left in his piggy bank after a year, how much money, in dollars, did he have at first?
Randy spends 2 * 4 = 8 dollars every month. Randy spends 8 * 12 = 96 dollars in a year. Randy had 96 + 104 = 200 dollars in his piggy bank at first.
The final answer: 200.
