Question: Lauren wanted to make burgers and fries for dinner. She needed a few things from the grocery store and bought the following: 2 pounds of hamburger meat that was on sale for $3.50 a pound. 1 pack of hamburger buns for $1.50. A head of lettuce for $1.00 and a large 1.5-pound tomato that was priced at $2.00 per pound. She also needed a jar of pickles that cost $2.50 and she had a $1.00 off coupon for that item. How much change would Lauren get back if she paid with a $20 bill?
Answer: She bought 2 pounds of hamburger meat at $3.50 per pound so 2 * 3.50 = $7.00. The tomato weighed 1.5 pounds and cost $2.00 per pound so 1.5 * 2 = $3.00. When you add up all her items she spent 7 + 1.50 + 1 + 3 + 2.50 = $15.00. Her items added up to $15.00 and she had a $1.00 coupon off pickles so 15 - 1 = $14.00. She paid with a $20.00 bill so 20 - 14 = $6.00 in change. The answer is 6.
[Question]Jerry works as an independent contractor for a company that pays him $40 per task. If each task takes him two hours to complete and he works 10 hours a day for a whole week, calculate the total amount of money he would earn at the end of the week.
[Answer]If a task takes two hours to complete and Briar works for ten hours a day, he manages to complete 10 / 2 = five tasks a day. Since each task pays him $40, for the five tasks, he makes $40 * 5 = $200. If he works for a whole week, he makes $200 * 7 = $1400. The answer is 1400.
Q: Ashley wants a champagne toast at her wedding. She wants to serve 2 glasses of champagne to each of her 120 wedding guests. 1 bottle of champagne has 6 servings. How many bottles of champagne will she need?
A: She wants to serve 2 glasses of champagne to each of her 120 wedding guests so that's 2 * 120 = 240 servings. Each bottle holds 6 servings and she needs 240 servings so that's 240 / 6 = 40 bottles of champagne. The answer is 40.
Question: Michelle had some leftover cans of silly string from her birthday party. She split them among Roger and 3 of his friends. Then Roger decided to give 2 of his cans to his brothers so that he now has 4 for himself. How many cans of silly string did Michelle have to start with?
Answer: Roger originally had 4 cans of silly string + 2 can he gave to his brothers = 6 cans. Since his friends received the same amount as Roger did originally, 3 friends x 6 cans of silly string = 18 cans. Michelle started with 6 cans that went to Roger + 18 cans that went to his friends = 24 cans of silly string. The answer is 24.
[Question]Janet has 1/3 of a bottle of rose shampoo and 1/4 of a bottle of jasmine shampoo. If she uses 1/12 of a bottle of shampoo per day, how many days will her shampoo last?
[Answer]First cross - multiply to give both fractions the same denominator, then add the fractions: 1 / 3 + 1 / 4 = 4 / 12 + 3 / 12. Then add these fractions to find that she has 4 / 12 + 3 / 12 = 7 / 12 of a bottle of shampoo left. Then divide the total amount of shampoo she has by the amount she uses per day to find the number of days the shampoo will last: 7 / 12 / 1 / 12 / day = 7 days. The answer is 7.
[Question]Nancy agreed to pay 40% of the cost of her daughter's car insurance, which costs $80 a month. How much will Nancy pay each year?
[Answer]
First calculate Nancy's monthly portion of the car insurance by multiplying the total cost by 40%: .4 * $80 = $32. Then multiply the monthly cost by 12 to find the annual cost: $32 * 12 = $384. The answer is 384.
