Q: In a school garden, there are flowers in different colors. In total there are 96 flowers of four colors: green, red, blue, and yellow. There are 9 green flowers and three times more red flowers. Blue flowers make up to 50% of the total flower count. How many yellow flowers are there?
A: There are 3 * 9 = 27 red flowers. 50 / 100 * 96 = 48 flowers are blue. Knowing that, there are 96 - 48 - 27 - 9 = 12 yellow flowers in a school's garden. The answer is 12.
Question: Kim plants 80 cherry pits. 25% of them sprout and Kim sells 6 of the saplings. How many cherry saplings does she have left?
Answer: First find the number of saplings that sprout: 80 pits * 25% = 20 saplings. Then subtract the number she sold to find the number she has left: 20 saplings - 6 saplings = 14 saplings. The answer is 14.
[Question]Michael and Thomas are selling their lego collections. They agree to split any money they earn. They sell them based on how many circles are on top. Each circle costs 1 cent. They earned $5 each after selling 100 single pieces, 45 double pieces, 50 triple pieces and a number of quadruple pieces. How many quadruple pieces did they sell?
[Answer]They made $10 because 2 x 5 = 10. They made $1 off single pieces because 100 x .01 = 1. They made $.9 off double pieces because 45 x .02 = .9. They made $1.5 off triple pieces because 50 x .03 = 1.5. They earned $3.4 off the first three types because 1 + .9 + 1.5 = 3.4. They earned $6.6 off the quadruple pieces because 10 - 3.4 = 6.6. They sold 165 quadruple pieces because 6.6 / .04 = 165. The answer is 165.
Q: Eliza has 4 siblings. The total height of all 5 siblings combined is 330 inches. Two of her siblings are both 66 inches tall. Another sibling is 60 inches tall. If Eliza is 2 inches shorter than the last sibling, how tall is Eliza?
A: The first three siblings are 66 + 66 + 60 = 192 inches tall. Since the total of all the siblings is 330 inches, Eliza and the last sibling are 330 - 192 = 138 inches tall combined. If Eliza's height = h, 138 inches = h + (h + 2). (138 - 2) / 2 = 68 inches. Eliza is 68 inches tall. The answer is 68.
Question: Cassandra bought four dozen Granny Smith apples and used them to make four apple pies. She cut each pie into 6 large pieces. How many apples are in each slice of pie?
Answer: Four dozen apples contain 4 * 12 = 48 apples. Four pies, each cut into 6 pieces, contain 4 * 6 = 24 pieces. Thus, there are 48 / 24 = 2 apples in every slice of Cassandra's apple pie. The answer is 2.
Q: The lunchroom is full of students: 40% are girls and the remainder are boys. There are 2 monitors for every 15 students. There are 8 monitors. Every boy drinks, on average, 1 carton of milk, and every girl drinks, on average, 2 cartons of milk. How many total cartons of milk are consumed by the students in the lunchroom?
A:
There is 1 monitor for every fifteen students because 30 / 2 = 15. There are 120 students because 8 x 15 = 120. 60% of the lunchroom is boys because 100 - 40 = 60. There are 72 boys because 120 x .6 = 72. There are 48 girls because 120 x .4 = 48. The boys drink 72 cartons of milk because 72 x 1 = 72. The girls drink 96 cartons of milk because 48 x 2 = 96. They drink 168 cartons of milk because 72 + 96 = 168. The answer is 168.
