Reconstruct a question, answer pair from this explanation: 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.

Q: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?
