Question: Melony makes $21 of profit every time she sells 3 shirts and four times as much profit when she sells two pairs of sandals. How much profit will she make if she sells 7 shirts and 3 pairs of sandals?
Answer: Melony makes $21 * 4 = $84 of profit for two pairs of sandals. Melony makes $84 / 2 pairs = $42 of profit per pair of shoes. Melony makes $21 / 3 shirts = $7 of profit per shirt. For seven shirts, Melony will make 7 shirts * $7 = $49 of profit. For three pairs of sandals, Melony will make 3 pairs * $42 / pair = $126 of profit. Melony will make a total of $49 + $126 = $175 of profit. The answer is 175.
[Question]Thomas started saving for a car almost 2 years ago. For the first year, his weekly allowance was $50. In the second year, he got a job that pays $9 an hour at a coffee shop and worked 30 hours a week, so his parents discontinued his allowance. If the car he wants to buy is $15,000 and he spends $35 a week on himself, how much more money does Thomas need to buy the car by the end of the 2 years?
[Answer]There are 52 weeks in a year. For the first year, Thomas received 52 x 50 = $2600. In the second year, Thomas earned 9 x 30 = $270 a week. In a year, Thomas earned 52 x 270 = $14,040. The total for the two years is 14040 + 2600 = 16640. In 2 years, Thomas' weekly expenses amounted to $35 x (52 x 2) = $35 x 104 = $3640. By the end of 2 years, Thomas would have saved $16640 - $3640 = 13000. Thomas still needs $15,000 - 13000 = $2000. The answer is 2000.
Q: At camp Wonka, there are 96 campers. Two-thirds of the campers are boys, and the remaining one-third are girls. 50% of the boys want to toast marshmallows and 75% of the girls want to toast marshmallows. If each camper gets one marshmallow to toast, how many marshmallows do they need?
A: The girls make up one - third of the campers, so there are 96 / 3 = 32 girls. The boys make up two - thirds of the campers, so there are 32 + 32 = 64 boys. There are 32 x 75% = 24 girls who want to toast marshmallows. There are 64 x 50% = 32 boys who want to toast marshmallows. They need 24 + 32 = 56 marshmallows. The answer is 56.
Question: The world record for longest fingernails is 26 inches. Sandy, who just turned 12 this month, has a goal for tying the record. Her fingernails are 2 inches long. Her fingernails grow at a rate of one-tenth of an inch per month. How old will she be when she achieves the world record?
Answer: Sandy's fingernails will grow a total of ( 0.1 ) * 12 = 1.2 inches per year. To achieve the world record, Sandy needs to grow her fingernails a total of 26 - 2 = 24 inches. It will take her a total of 24 / 1.2 = 20 years. Sandy will be 12 + 20 = 32 years old when she achieves the world record. The answer is 32.
[Question]Tommy has a flag that is 5 feet wide and 4 feet tall. He wants to paint it with a new design. He knows from experience that he needs to paint both sides. Paint costs $2 a quart and a quart is good for 4 square feet. How much does he spend on paint?
[Answer]Each side of the flag is 20 square feet because 5 x 4 = 20. Both side total to 40 square feet because 2 x 20 = 40. He will need 10 quarts because 40 / 4 = 10. This will cost $20 because 10 x 2 = 20. The answer is 20.
[Question]Archie holds the school record for most touchdown passes with 89 in a season of 16 games. Richard is close to breaking the record, having averaged 6 touchdowns a game in the first 14 games. How many touchdowns per game must he average in the final two games to beat Archie's record?
[Answer]
Richard has scored 84 touchdowns because 14 x 6 = 84. To beat the record he must score 90 touchdowns because 89 + 1 = 90. He needs 6 more touchdowns to beat the record because 90 - 84 = 6. He has two games left because 16 - 14 = 2. He needs to average 3 touchdowns a game to beat the record because 6 / 2 = 3. The answer is 3.
