Reasoning and answer: 1. Tonya sold $11 worth of small lemonades and $24 worth of medium lemonades which makes $11 + $24 = $35 for small and medium lemonades. 2. Tonya made a total of $50. If she made $35 selling the two smaller sizes and she sold three sizes in all then $50 - $35 = $15 worth of large lemonades. 3. The large lemonades sold for $3 each and Tonya sold $15 worth of large lemonades which means she sold $15 / $3 = 5 large cups of lemonade.
The answer: 5

The chef had 17 - 12 = 5 meals left after lunch. So, the chef has 5 + 5 = 10 meals for dinner.
The answer: 10
Reverse engineering the question: In a restaurant, the chef prepared 17 meals to sell for lunch. During lunch, he sold 12 meals. After lunch, the chef prepared another 5 meals for dinner. How many meals does the chef have for dinner, assuming he can use the remaining lunch meals as well?


Reasoning and answer: A total of 4 + 6 = 10 cars are in the shop throughout the week. This means the shop buys 10 cars * 4 tires = 40 tires. For each of the customers that only want half the tires changing, there are 4 tires * 0.5 = 2 tires left over. Two of the customers only want half the tires changing, so there are 2 tires * 2 cars = 4 tires left over from these customers. Out of the remaining tires, there are 20 – 4 = 16 tires left from customers who don't want their tires changing. So in total, there were 16 tires / 4 tires per customer = 4 customers who did not want their tires changing.
The answer: 4

Question: An auto shop buys tires to replace all the tires on every customer’s car. They buy the tires as soon as cars are brought into the shop. There are four cars in the shop already, and another six customers come into the shop throughout the week. Some of the customers decide they don't want any of the tires changing, and two customers decide they only want half the tires changing. They had no tires in stock at the start of the week. If the shop has 20 tires left at the end of the week, how many customers decided they did not want their tires changing?


He spends 3 * 25 = $75 each time he plays. So he spends 75 * 3 = $225.

Reasoning and answer: The couple want 3 slices each for a total of 2 * 3 = 6 slices. The children want 1 slice each for a total of 1 * 6 = 6 slices. They want 6 + 6 = 12 slices in total. Each pizza has 4 slices so they need 12 / 4 = 3 pizzas.
The answer: 3

Question: A married couple and their 6 children are ordering some pizza. If the couple want 3 slices each and the children want 1 slice each, how many 4-slice pizzas should they order?


Reasoning and answer: The trip to the supermarket and back home covers 5 + 5 = 10 miles. The round trip of two miles each before he actually went to the farm covers 2 + 2 = 4 miles. Six miles to the farm and the total mileage is 10 + 4 + 6 = 20 miles. The truck consumed 12 - 2 = 10 gallons of gasoline for the total journey. So, the rate is 20 / 10 = 2 miles per gallon.
The answer: 2

Question:
Bobby needed to make some trips with his truck and had only 12 gallons of gasoline. He drives to a supermarket 5 miles away and then drives back home. Then he headed to his farm which was 6 miles away. Two miles into the journey, he turned around and drove back home to retrieve some farming tools he forgot to take earlier and drove down to the farm. If he now has exactly 2 gallons of gasoline left, at what rate in miles per gallon has his truck been consuming gasoline?
