Question: Carla has 6 sunflowers and 8 dandelions. The sunflowers have 9 seeds per plant and the dandelions have 12 seeds per plant. What percentage of Carla's seeds come from the dandelions?
Answer: First calculate the number of seeds from the sunflowers by multiplying the number of sunflowers by the number of seeds per sunflower: 6 sunflowers * 9 seeds / sunflower = 54 seeds. Next calculate the number of seeds from the dandelions by multiplying the number of dandelions by the number of seeds per dandelion: 8 dandelions * 12 seeds / dandelion = 96 seeds. Now add the number of seeds from each group of plants to find the total number of seeds: 54 seeds + 96 seeds = 150 seeds. Now divide the number of dandelion seeds by the total number of seeds and multiply the answer by 100 to find the percentage of seeds that come from the dandelions: 96 seeds / 150 seeds * 100% = 64%. The answer is 64.

Question: Keith scored 3 points on the math test. Larry scored 3 times as many marks. Danny scored 5 more marks than Larry. Find the total amount of marks scored by the three students.

Question: Jerry can run from his house to his school and back in the time it takes his brother Carson to run to the school. If it takes Jerry 15 minutes to make a one-way trip from his house to his school and the school is 4 miles away, how fast does Carson run in miles per hour?
Answer: We know that Carson takes twice as long as Jerry to get to the school, so we can find the time it takes him by multiplying Jerry's time by 2: 15 minutes * 2 = 30 minutes. Then convert that time to house by dividing by 60 minutes / hour = 30 minutes / 60 minutes / hour = .5 hour. Then divide the distance Carson runs by the time it takes him to run it to find his speed: 4 miles / 0.5 hours = 8 miles / hour. The answer is 8.

Question: There are two babysitters named Mila and Agnes. Mila makes $10 an hour while Agnes makes $15 an hour. Agnes works 8 hours each week. How many hours does Mila need to work to earn as much as Agnes in a month?
Answer:
The weekly salary of Agnes is $15 x 8 = $120. So in a month, Agnes earns $120 x 4 = $480. Therefore, Mila needs to work for $480 / $10 = 48 hours to earn as much as Agnes's monthly earnings. The answer is 48.
