Reasoning and answer: Allie has 9 - 1 = 8 toys of the same value. Without the value of the one $12 toy, all 8 other toys are worth in total 52 - 12 = $40. That would mean, that one of the other toys is worth 40 / 8 = $5.
The answer: 5

Question: Allie has 9 toys, which are in total worth $52. If we know that one toy is worth $12, and all the other toys have the same value, how much does one of the other toys cost?
Combining Monday and Friday, Leila ate 6 + 9 = 15 cakes. On Saturday, she ate 6 * 3 = 18 cakes. Altogether, Leila ate 15 + 18 = 33 cakes.
The answer: 33
Reverse engineering the question: Leila eats cake almost every week. Last week, she ate 6 cakes on Monday, 9 cakes on Friday, and on Saturday, she ate triple the number of cakes she ate on Monday. How many cakes does Leila eat?
Reasoning and answer: First figure out how many city miles Carl will drive round trip by multiplying the one - way number of city miles by 2: 60 miles * 2 = 120 miles. Then figure out how many highway miles Carl will drive round trip by multiplying the one - way number of highway miles by 2: 200 miles * 2 = 400 miles. Now divide the round - trip number of city miles by the number of city miles per gallon Carl's car gets: 120 miles / 30 mpg = 4 gallons. Now divide the round - trip number of highway miles by the number of highway miles per gallon Carl's car gets: 400 miles / 40 mpg = 10 gallons. Now add the gallons for the highway miles and the city miles to find the total number of gallons Carl needs to buy: 10 gallons + 4 gallons = 14 gallons. Finally, multiply the number of gallons Carl needs to buy by the cost per gallon to find out how much he spends: 14 gallons * $3.00 = $42.00.
The answer: 42

Question: Carl is figuring out how much he'll need to spend on gas for his upcoming road trip to the Grand Canyon. His car gets 30 miles per gallon in cities and 40 miles per gallon on the highway. The distance from his house to the Grand Canyon, one way, is 60 city miles and 200 highway miles. If gas costs $3.00 per gallon, how much will Carl need to spend?
Marianne is 20 - 8 = 12 years older than Bella. Bella will turn 18 in 18 - 8 = 10 years. So, Marianne will be 20 + 10 = 30 years old then.
The answer: 30
Reverse engineering the question: Marianne was 20 years old when Bella was 8 years old. How old will Marianne be when Bella turns 18?
Reasoning and answer: There were an average of 40 + 50 = 90 apples. And, there were 30 + 40 = 70 oranges. Thus, Wendy gained 90 x $1.50 = $135 for selling apples. And, she gained an additional 70 x $1 = $70 for selling oranges. Therefore, her total sales for the day is $135 + 70 = $205.
The answer: 205

Reasoning and answer: Officer A patrols 36 streets / 4 hours = 9 streets / hour. Officer B patrols 55 streets / 5 hours = 11 streets / hour. Together officer A and B patrol 9 streets / hour + 11 streets / hour = 20 streets / hour.
The answer: 20
