[Question]Hannah is buying some apples for $5 per kilogram. If she would get a 40% discount on each kilogram of apples, how much would she pay for 10 kilograms of them?
[Answer]A 40% discount on each kilogram of apples would mean the price being 40 / 100 * 5 = $2 smaller. So one kilogram of apples would cost not $5, but 5 - 2 = $3. So for 10 kilograms of apples Hannah would pay 3 * 10 = $30. The answer is 30.
Q: Michael has a chicken farm. His chickens increase in number by 150 chickens annually. If the number of chickens on his farm now is 550, how many will he have after 9 years?
A: The number of the increase in chicken after 9 years is 150 * 9 = 1350. So the total number of the chicken in Michael's farm will be 550 + 1350 = 1900. The answer is 1900.
Question: It takes Jerome 6 hours to run the trail around the park and it takes Nero 3 hours. If Jerome runs at 4 MPH, what speed (in MPH) does Nero run in the park?
Answer: You can find the distance of Jerome's run by multiplying the time he spends running by his speed: 4 miles / hour * 6 hours = 24 miles. Then find Nero's speed by dividing the distance he runs by the time he spends running: 24 miles / 3 hours = 8 miles / hour. The answer is 8.

Question: Hershel has 10 betta fish and 15 goldfish in a bowl. His friend Bexley brings him 2/5 times as many betta fish and 1/3 times as many goldfish. If Hershel gifts his sister 1/2 of the fish, calculate the total number of fish he has remaining in the bowl.
Answer:
Bexley gives Hershel 2 / 5 * 10 = 4 betta fish. The total number of betta fish in the bowl is now 4 + 10 = 14. He also gives Hershel 1 / 3 * 15 = 5 goldfish. The total number of goldfish in the bowl is now 15 + 5 = 20. Counting the betta fish and goldfish, Hershel now has a total of 14 + 20 = 34 fish. When he gives his sister half of the fish, the remaining half is 34 / 2 = 17 fish. The answer is 17.
