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