Question: Megan pays $16 for a shirt that costs $22 before sales. What is the amount of the discount?
Answer: Let x be the amount of the discount. We have, 22 - x = $16. We change the writing of the equation:. 22 - x + x = 16 + x. So, 22 = 16 + x. We then Remove 16 from both sides:. 22 - 16 = 16 + x - 16. So, 22 - 16 = x. So, the amount of the discount is x = $6. The answer is 6.

Question: 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?
Answer: 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. The answer is 50.

Question: Jenny's local library received 50 visitors on Monday. On Tuesday, the library received twice that number. On the remaining days of the week, an average of 20 visitors went to the library. What's the total number of visitors who went to the library that week?
Answer:
On Monday, there were 50 visitors. On Tuesday, there were twice as many, so 2 * 50 = 100 visitors. The total number of visitors after Tuesday will be 100 + 50 = 150 visitors. For the remaining 5 days, an average of 20 visitors attended, giving a total of 5 * 20 = 100 visitors. The total number of visitors who visited the library for the week was 100 + 150 = 250 visitors. The answer is 250.
