[Question]Valerie needs to put stamps on the envelopes she is about to mail. She has thank you cards for each of her grandmother, uncle and aunt for the birthday presents they sent. She also has to pay the water bill and the electric bill separately. She wants to send three more mail-in rebates than she does bills and she has twice as many job applications as rebates to mail. How many stamps does she need if everything needs 1 stamp except the electric bill, which needs 2?
[Answer]Valerie has to send a thank you card to each of 3 people, so she has 3 * 1 = 3 thank you cards to mail. She has 2 bills to mail. She has 3 more rebates than bills, so 3 + 2 = 5 mail - in rebates to mail. She has twice as many job applications as rebates, so she has 2 * 5 = 10 applications to mail. She has 3 + 2 + 5 + 10 = 20 pieces of mail to send. The electric bill needs an extra stamp, so she needs 20 + 1 = 21 stamps. The answer is 21.
Q: A family's water and electricity bills average $30 a month for the first 4 months and $24 a month for the last 2 months. If the family's bills were averaged over all 6 months, what would the average monthly bill be?
A: The sum of the bills of the family in the first 4 months is $30 / month x 4 months = $120. The sum of the bills of the family in the last 2 months is $24 / month x $2 = $48. The sum of the bills of the family over the 6 months is $120 + $48 = $168. Hence, their average monthly bill is $168 / 6 months = $28 / month. The answer is 28.
Question: At a roller derby, 4 teams are competing. Each team is made up of 10 members, and each member needs a pair of roller skates to compete in and another pair of skates as a backup. None of the skates have laces yet, so each member is offered 3 sets of laces per pair of skates. How many sets of laces have been handed out?
Answer: There are a total of 4 teams * 10 members per team = 40 team members. Each person receives 1 pair of competing roller skates + 1 pair of backup roller skates = 2 pairs of roller skates. So there are a total of 40 team members * 2 pairs of roller skates per team member = 80 roller skates. There were therefore 80 roller skates * 3 sets of laces per pair of roller skates = 240 sets of laces handed out. The answer is 240.
[Question]Carter can read half as many pages as Lucy in 1 hour. Lucy can read 20 more pages than Oliver in 1 hour. Oliver can read 40 pages. How many pages can Carter read in 1 hour?
[Answer]Lucy can read 20 more pages than Oliver who can read 40 pages so Lucy can read 40 + 20 = 60 pages. Carter can read half as many pages as Lucy who can read 60 pages so he can read 60 / 2 = 30 pages in 1 hour. The answer is 30.
Q: Victor works at Clucks Delux, a restaurant specializing in chicken. An order of Chicken Pasta uses 2 pieces of chicken, an order of Barbecue Chicken uses 3 pieces of chicken, and a family-size Fried Chicken Dinner uses 8 pieces of chicken. Tonight, Victor has 2 Fried Chicken Dinner orders, 6 Chicken Pasta orders, and 3 Barbecue Chicken orders. How many pieces of chicken does he need for all the orders?
A: Victor needs 2 * 8 = 16 pieces of chicken for Fried Chicken Dinners. He needs 6 * 2 = 12 pieces of chicken for Chicken Pasta. He needs 3 * 3 = 9 pieces of chicken for Barbecue Chicken orders. Thus, he needs 16 + 12 + 9 = 37 pieces of chicken. The answer is 37.
Question: Tricia buys large bottles of iced coffee that have 6 servings per container. She drinks half a container a day. The coffee is currently on sale for $3.00 a bottle. How much will it cost her to buy enough bottles to last for 2 weeks?
Answer:
She drinks half a container of a 6 serving bottle of iced coffee a day so she drinks 6 / 2 = 3 servings a day. There are 7 days in a week and she needs enough bottles to last for 2 weeks so that's 7 * 2 = 14 days. She drinks 3 servings a day for 14 days so that's 3 * 14 = 42 servings. Each bottle holds 6 servings and she drinks 42 servings in a week so she needs 42 / 6 = 7 bottles. The iced coffee is on sale for $3.00 a bottle and she needs 7 bottles for a total of 3 * 7 = $21.00. The answer is 21.
