Hi there! So an allergy medicine costs $130 each month, which when you multiply 130 * 12, you get 1,560. That's $1,560 on that medicine spent per year, However, you have to pay $4 monthly as the co-payment and 4 * 12 is 48. Now, let's subtract the co-payment from the amount of the medicine spent per year. 1,560 - 48 = 1,512. You will save $1,512 dollars in 1 year by buying the generic version. The answer is A: $1,512.
