[Question]: Maria went on a trip to Belgium. She paid $300 for the ticket and half of that for the hotel. How much money does she have left, when she had $760 at the beginning?
[Answer]: For the hotel Maria paid 300 / 2 = $150. So Maria has 760 - 300 - 150 = $310 left.
So the answer is 310.

[Question]: Happy Cattle Ranch is home to 200 cows. Every year, the mother cows have enough calves that the number of cows the rancher owns rises by half the number of cows living on the ranch. If the rancher does not buy or sell any cows, how many cows will the rancher own on Happy Cattle Ranch in two years?
[Answer]: In one year, the rancher will have 200 + 200 / 2 = 200 + 100 = 300 cows. In two years, the rancher will have 300 + 300 / 2 = 300 + 150 = 450 cows.
So the answer is 450.

[Question]: Jimmy is going to sell pizzas at the carnival to make some money. The carnival only gave him 7 hours to do so. He bought a 22kg sack of flour to make his pizzas and he takes 10 min to make each pizza for the customers. At the end of the 7 hours, he saw some flour was left. Knowing that each pizza needs 0.5kg of flour to make, how many pizzas can he make to bring home with the flour left?
[Answer]:
Each hour Jimmy makes 60min 10min / pizza = 6 Pizzas. The number of total pizzas made equals 7 hours x 6 pizzas / hour = 42 pizzas. The amount of total flour used equals 42 pizzas x 0.5 kg / pizza = 21 kg. The amount of flour left equals 22 kg - 21 kg = 1 kg. The number of pizzas Jimmy can make is 1kg 0.5kg / pizza = 2 pizzas.
So the answer is 2.
