Using coupons, you spend $120 grocery shopping. this is 80% of the total retail price of the groceries. how much would you have spent if you had not used the coupons?

If I remember correctly, you do 80% times 120 which is 96. So, 96 dollars is what you saved. Now, to find what you would have spent without the coupons, you have to add what you saved ($96) to 120 which is $216. Someone please correct me if I'm wrong. I do not want to be giving false information if I had done something incorrectly. But I am confident that is how you do this problem.
