Hayden eats 1 oz of mixed nuts as an evening snack. He buys the bulk bag of mixed nuts that cost $25.00 a bag and holds 40 oz of mixed nuts. There is currently a $5.00 coupon for this item. How much will each serving of nuts cost, in cents, after the coupon is applied?
Thoughts? Step-by-step reasoning:
The nuts are $25.00 and he has a $5.00 coupon, so the nuts are on sale for $25 - $5 = $20.00. He eats 1 oz of nuts every evening and the bag has 40 oz of nuts, so it has 40 / 1 = 40 1 oz servings. The nuts cost $20.00 and there are 40 servings per bag, so his snack is $20 / 40 = $0.50 per serving.
Thus, the answer is 50.
