Tim has 68 - 30 = 38 apples. Harry has 38 / 2 = 19 apples.
The answer: 19
Reverse engineering the question: Tim has 30 less apples than Martha, and Harry has half as many apples as Tim. If Martha has 68 apples, how many apples does Harry have?
Reasoning and answer: The cost of Gary's gold is 30 * $15 = $450. The cost of Anna's gold is 50 * $20 = $1000. The total cost of their gold is $450 + $1000 = $1450.
The answer: 1450
What was the question?
Question: Gary has 30 grams of gold that cost $15 per gram. Anna has 50 grams of gold for the cost of $20 per gram. How much is the cost of their gold combined?
If one meatball is made from 1 / 8 pound of hamburger meat, then 4 pounds of hamburger meat will make 4 / (1 / 8) = 4 * 8 = 32 meatballs. 32 meatballs divided amongst 8 family members is 32 / 8 = 4 meatballs per family member.
The answer: 4
Reverse engineering the question: Antonio is preparing a meal of spaghetti and meatballs for his family. His recipe for meatballs calls for 1/8 of a pound of hamburger per meatball. Antonio has 8 family members, including himself. If he uses 4 pounds of hamburger to make meatballs, and each member of the family eats an equal number of meatballs, how many meatballs will Antonio eat?
Reasoning and answer: Let H = Hezekiah's age. Ryanne = H + 7. 2H + 7 = 15. 2H = 8. H = 4. Hezekiah is 4 years old.
The answer: 4
What was the question?
Question: Ryanne is 7 years older than Hezekiah. Together Ryanne's and Hezekiah's ages equal 15 years. How many years old is Hezekiah?
Oliver's $20 bills amount to $20 x 10 = $200. Oliver's $5 bills amount to $5 x 3 = $15. So, Oliver has a total of $200 + $15 = $215. William's $10 bills amount to $10 x 15 = $150. William's $5 bills amount to $5 x 4 = $20. So, William has a total of $150 + $20 = $170. Therefore, Oliver has $215 - $170 = $45 more than William.
The answer: 45
Reverse engineering the question: Oliver has 10 $20 and 3 $5 bills. William has 15 $10 and 4 $5 bills. How much more money does Oliver have than William?
His dog gets 1 carrot a day and there are 365 days in a year, so his dog eats 1 * 365 = 365 carrots. There are 5 carrots per bag and he will need 365 carrots, so that's 365 / 5 = 73 bags of carrots. The bags cost $2.00 and he will need 73 bags so that's $2 * 73 = $146.00 worth of organic carrots.
The answer: 146
Reverse engineering the question:
Harris feeds his dog 1 large organic carrot over the course of 1 day. There are 5 carrots in a 1 pound bag and each bag costs $2.00. In one year, how much will Harris spend on carrots?
