Q: Steve has a bank account that earns 10% interest every year. He puts $100 in it, and then 10 each year. How much money is in it after two years?
A: After one year it earns $10 in interest because 100 x .1 = 10. It has $120 in it after a year because 100 + 10 + 10 = 120. In the second year it earns $12 in interest because 120 x .1 = 12. In the second year it has $142 in it because 120 + 12 + 10 = 142. The answer is 142.
Question: Amoli and Anayet must travel 369 miles together. Amoli drove 42 miles an hour for 3 hours and Anayet drove at 61 miles an hour for 2 hours. How many miles do they still need to travel?
Answer: Amoli = 42 * 3 = 126 miles. Anayet = 61 * 2 = 122. Together = 126 + 122 = 248 miles. 369 - 248 = 121 miles. They still have 121 miles to travel. The answer is 121.
[Question]Mr Julien's store has 400 marbles remaining after the previous day's sales. Twenty customers came into the store, and each bought 15 marbles. How many marbles remain in the store?
[Answer]If each of the 20 customers bought 15 marbles, then they bought 20 * 15 = 300 marbles in total from Mr Julien's store. The number of marbles remaining in the store is 400 - 300 = 100 marbles. The answer is 100.
Q: Haley grows at the rate of 3 inches every year. If she is currently 20 inches tall, what will be her height after 10 years?
A: After 10 years, growing at the rate of 3 inches every year, Haley will have grown by 3 * 10 = 30 inches. If she is currently 20 inches tall, her height after 10 years will be 20 + 30 = 50 inches. The answer is 50.
Question: Apple and peach trees are planted in the orchard of the Grange Poser farm. The orchard has 30 apple trees that each give 150 kg of apples and 45 peach trees that each produce an average of 65 kg of fruit. What is the total mass of fruit harvested in this orchard?
Answer: Let’s first calculate what the apple trees produce: 30 trees * 150 kg / tree = 4500 kg. Then let's calculate what the peaches produce: 45 trees * 65 kg / tree = 2925 kg. We add these two masses: 4500 kg + 2925 kg = 7425 kg. The answer is 7425.
Q: John eats 3 meals a day. Breakfast is 500 calories. His lunch contains 25% more calories than that. His dinner is twice as many calories as lunch. He also has 3 shakes that are each 300 calories. How many calories does he get in a day?
A:
Lunch is 500 * .25 = 125 more calories than breakfast. That means it is 500 + 125 = 625 calories. So dinner is 625 * 2 = 1250 calories. The shakes are 3 * 300 = 900 calories. So in total he eats 500 + 625 + 1250 + 900 = 3275 calories. The answer is 3275.
