Q: The total average age of three friends is 40. Jared is ten years older than Hakimi, and Molly's age is 30. How old is Hakimi?
A: The total age for the three friends is 40 * 3 = 120. If Molly's age is 30, then Jared and Hakimi have a total age of 120 - 30 = 90. Let's say the age of Hakimi is x. Since Jared is 10 years older than Hakimi, Jared is x + 10 years old. Jared and Hakimi's total age is x + (x + 10) = 90. This translates to 2x = 90 - 10. 2x = 80. Hakimi's age is x = 80 / 2. This gives us x = 40, which is Hamkimi's age. The answer is 40.
Question: A pound of strawberries costs $2.20 and a pound of cherries costs 6 times as much as strawberries. If Briget will buy 5 pounds of strawberries and 5 pounds of cherries, how much will it cost?
Answer: Five pounds of strawberries cost $2.20 x 5 = $11. A pound of cherries costs $2.20 x 6 = $13.20. Five pounds of cherries cost $13.20 x 5 = $66. Therefore, it will cost Briget a total of $11 + $66 = $77. The answer is 77.
[Question]Bill is laying power cable for a new neighborhood. There are going to be 18 east-west streets that are 2 miles long and 10 north-south streets that are four miles long. It takes 5 miles of cable to electrify 1 mile of street. If cable costs $2000/mile, what is the total cost of cable for the neighborhood?
[Answer]First find the total distance of the east - west streets: 18 streets * 2 miles / street = 36 miles. Then find the total distance of the north - south streets: 10 streets * 4 miles / street = 40 miles. Then add the number of miles from each type of street to find the total distance: 36 miles + 40 miles = 76 miles. Then multiply that number by 5 to find the number of miles of cable needed: 76 miles street * 5 miles cable / mile street = 380 miles of cable. Then multiply that number by the cost of one mile of cable to find the total cost: 380 miles * $2000 / mile = $760,000. The answer is 760000.
Q: Gary is buying chlorine for his rectangular pool, which is 10 feet long, 8 feet wide, and 6 feet deep. Gary needs to buy one quart of chlorine for every 120 cubic feet of water in his pool. If chlorine costs $3 a quart, how much does Gary spend on chlorine?
A: First find the volume of the pool by multiplying the length by the width by the height: 10 ft * 8 ft * 6 ft = 480 cubic feet. Then divide the volume of the pool by the number of cubic feet one quart of chlorine can sterilize: 480 cubic feet / 120 cubic feet / quart = 4 quarts. Then multiply the number of quarts Gary needs to buy by the price per quart to find out how much money he spends: $3 / quart * 4 quarts = $12. The answer is 12.
Question: Candied yams fly off the shelf during the holiday season. The store buys them in bulk boxes of 25 packages. If every third shopper buys a package of candied yams, how many bulk boxes of candied yams will the store need to order for their 375 predicted holiday shoppers?
Answer: Every third shopper buys a package of candied yams, so the store will need 375 / 3 = 125 packages. At 25 packages per bulk box, the store will need 125 / 25 = 5 bulk boxes of candied yams. The answer is 5.
