The savory souffles need 8 eggs each and she wants to make 3 of these so she needs 8 * 3 = 24 eggs. The dessert souffles need 6 eggs each and she wants to make 5 of these so she needs 6 * 5 = 30 eggs. For the dinner party she will need 24 + 30 = 54 eggs in total.
The answer: 54
Reverse engineering the question: Roberta wants to have a dinner party centered around souffles. Each savory souffle calls for 8 eggs each and the dessert ones call for 6 eggs each. She wants to make 3 savory souffles and 5 dessert souffles for the party. How many eggs will she need?
Reasoning and answer: Divide the remaining miles of the trip by the miles per gallon her car gets. 220 miles / 20 miles / gallon = 11 gallons. Subtract the gallons used for the trip from the size of her gas tank. 16 gallons - 11 gallons = 5 gallons. Multiply the remaining number of gallons by the car's gas mileage. 5 gallons x 20 miles / gallon = 100 miles.
The answer: 100

Question: Carol fills up her gas tank as she is driving home for college, which is 220 miles away. She can get 20 miles to the gallon in her car, which has a 16-gallon gas tank. How many more miles will she be able to drive after she gets home and without filling her tank again?
Only 10 2 = 8 pieces of fruit were eaten this week. Subtracting Friday's snacks shows Mark ate 8 3 = 5 pieces of fruit in the first four days of the week.
The answer: 5
Reverse engineering the question: Mark had 10 pieces of fruit to eat in school this week. On Friday, he decided to keep 2 pieces of fruit for next week. He then brings the remaining 3 pieces of fruit to school for the day. How many pieces of fruit did Mark eat in the first four days of the week?
Reasoning and answer: The cafeteria used 100 lasagnas * 2 pounds of ground mince = 200 pounds of ground mince for the lasagnas. This means they used 500 pounds of ground mince in total 200 pounds of ground mince for the lasagnas = 300 pounds of ground mince for the cottage pies. So they must have made 300 pounds of ground mince for the cottage pies / 3 pounds of ground mince per cottage pie = 100 cottage pies.
The answer: 100
What was the question?
Question: A school cafeteria uses ground mince to cook lasagnas and cottage pies. They make 100 lasagnas, which use 2 pounds of ground mince each, and cottage pies, which use 3 pounds of ground mince each. If the cafeteria has used 500 pounds of ground mince in total, how many cottage pies did they make?
First find the total number of pieces of mail the post office receives per day: 60 letters + 20 packages = 80 pieces of mail. Then multiply the daily amount of mail by the number of days per month: 80 pieces / day * 30 days / month = 2400 pieces / month. Then multiply that number by 6 to find the total number of pieces of mail handled: 2400 pieces / month * 6 months = 14400 pieces.
The answer: 14400
Reverse engineering the question: The post office receives 60 letters and 20 packages per day. How many pieces of mail does it handle in six months if all the months have 30 days?
3 weeks translate to 3 * 7 days = 21 days. To meet Dr. Juan's recommendation would mean drinking 105 / 21 = 5 gallons daily. This means that Flora must drink 5 - 3 = 2 more gallons daily.
The answer: 2
Reverse engineering the question:
Flora has been experiencing frequent fractures. Dr. Juan has asked her to strengthen her bones by drinking 105 gallons of milk within 3 weeks. Flora thinks that drinking 3 gallons of milk daily will be enough, but her brother says she'll still need to drink more. To fulfill Dr. Juan's requirement, how many more gallons must Flora drink daily?
