Answer: A kilogram of chicken costs $6 - $2 = $4. Three kilograms of chicken cost $4 x 3 = $12. So, a 3 - kilogram of chicken and a kilogram of pork cost $12 + $6 = $18. The answer is 18.
[Question]Jack is on the phone with a scammer who says the IRS will arrest Jack if he doesn't send them the codes from 6 $500 Best Buy gift cards and 9 $200 Walmart gift cards. After sending the codes for 1 Best Buy gift card and 2 Walmart gift cards, Jack wises up and hangs up. How many dollars' worth of gift cards can he still return?
[Answer]First find the number of Best Buy gift cards Jack needs to return: 6 cards - 1 cards = 5 cards. Then multiply that number by the cost per card to find the total refund Jack gets from Best Buy: 5 cards * $500 / card = $2500. Then find the number of Walmart gift cards Jack needs to return: 9 cards - 2 cards = 7 cards. Then multiply that number by the cost per card to find the total refund Jack gets from Walmart: 7 cards * $200 / card = $1400. Then add the two refunds to find his total refund amount: $2500 + $1400 = $3900. The answer is 3900.
Q: Compared to the amount of water she drank, Carla drank three times as much soda minus 6 ounces. If she drank 54 ounces of liquid total, how much water did she drink?
A: Let s be the amount of soda Carla drank and w be the amount of water she drank. We know that s + w = 54 and s = 3w - 6. Substituting the second equation into the first, we get 3w - 6 + w = 54. Combining like terms, we get 4w - 6 = 54. Adding 6 to both sides, we get 4w = 60. Dividing both sides by 4, we get w = 15. The answer is 15.
Question: Jerry needs to shingle 3 roofs. Each roof is made of two slanted rectangular sides measuring 20 feet by 40 feet. If he needs 8 shingles to cover one square foot of roof, how many shingles does he need total?
Answer: First find the area of one side of a roof: 20 feet * 40 feet = 800 square feet. Then multiply that number by 2 to find the total area of both sides of the roof: 800 square feet / side * 2 sides = 1600 square feet. Then multiply that number by the number of roofs to find the total area of all the roofs: 1600 square feet / roof * 3 roofs = 4800 square feet. Then multiply the total area of the roofs by the number of shingles needed per square foot to find the total number of shingles needed: 4800 square feet * 8 singles / square foot = 38400 shingles. The answer is 38400.
[Question]Jenny has a tummy ache. Her brother Mike says that it is because Jenny ate 5 more than thrice the number of chocolate squares that he ate. If Mike ate 20 chocolate squares, how many did Jenny eat?
[Answer]Thrice the number of chocolate squares that Mike ate is 20 squares * 3 = 60 squares. Jenny therefore ate 60 squares + 5 squares = 65 chocolate squares. The answer is 65.
[Question]Amanda needs 12 more marbles to have twice as many marbles as Katrina, and Mabel has 5 times as many marbles as Katrina. If Mabel has 85 marbles, how many more marbles does Mabel have than Amanda?
[Answer]
Katrina has 85 / 5 = 17 marbles. Twice as many marbles as Katrina is 17 x 2 = 34. Amanda has 34 - 12 = 22 marbles. Mabel has 85 - 22 = 63 more marbles than Amanda. The answer is 63.
