Question: Melly's two cats each have litters of kittens at the same time. The first cat has 3 blue-eyed kittens and 7 brown-eyed kittens. The second cat has 4 blue-eyed kittens and 6 brown-eyed kittens. What percentage of all the kittens have blue eyes?
Answer: First find the total number of blue - eyed kittens: 3 kittens + 4 kittens = 7 kittens. Then find the total number of brown - eyed kittens: 7 kittens + 6 kittens = 13 kittens. Then add the number of each type of kitten to find the total number of kittens: 7 kittens + 13 kittens = 20 kittens. Then divide the number of blue - eyed kittens by the total number of kittens and multiply by 100% to express the answer as a percentage: 7 kittens / 20 kittens * 100% = 35%. The answer is 35.
[Question]In a city, the number of people living per cubic yard is 80. How many more people are in a city with 9000 cubic yards than a city with 6400 cubic yards?
[Answer]The difference in cubic yards between the two cities is 9000 - 6400 = 2600 cubic yards. Since the number of people living in a city per cubic yard is 80, there are 80 * 2600 = 208000 more people living in a city with 9000 cubic yards than a city with 6400 cubic yards. The answer is 208000.
Q: Sally is saving up for a trip to Sea World. She already has $28 saved. It costs her $10 to park, $55 to get into the park and $25 for a meal pass. Sea World is 165 miles away and her car gets 30 miles per gallon of gas. If gas costs $3 a gallon, how much more will she have to save up?
A: She will be driving 330 miles for her trip because 2 x 165 = 330. They will need 11 gallons of gas because 330 / 30 = 11. The gas will cost $33 because 11 x 3 = 33. Her total cost is $123 because 10 + 55 + 25 + 33 = 123. She needs to save $95 more because 123 - 28 = 95. The answer is 95.
Question: Jimmy and Tonya both like collecting matchbooks and stamps. Tonya and Jimmy decide to trade some stamps and matchbooks. They have each decided that one stamp is worth 12 matches. Each matchbook contains 24 matches. If Tonya arrives with 13 stamps, Jimmy has 5 matchbooks, and Jimmy trades all his matchbooks for stamps, how many stamps does Tonya have left?
Answer: Jimmy has 120 matches because 5 times 24 equals 120. Jimmy trades this for 10 stamps because 120 divided by 12 equals 10. Tonya has 3 stamps left because 13 minus 10 equals 3. The answer is 3.
[Question]Tony goes on 5 rollercoasters while he is at the park. The first went 50 miles per hour. The second went 62 miles per hour. The third when 73 miles per hour. The fourth when 70 miles per hour. His average speed during the day was 59 miles per hour. How fast was the fifth coaster?
[Answer]The total speed of all five coasters is 295 because 59 x 5 = 295. The final coaster went 40 miles per hour because 295 - 50 - 62 - 73 - 70 = 40. The answer is 40.
[Question]Cindy was 5 years old. Her sister Jan was 2 years older than Cindy. Their oldest sister Marcia was twice as old as Jan. Greg was two years older than Marcia. How old was Greg?
