We have a question: Six kids and two adults are going to the circus. Kid's tickets are on sale for only half of the adult tickets. The total cost is $50. How much is one kid's ticket?
And an answer: 5
So how you got the answer?
Let X be the price of one kid's ticket. So the price of one adult ticket is X * 2. Five kids and two adults are going to the circus, so 6 * X + 2 * (X * 2) = $50. So 10X = $50. So the price of one kid's ticket is X = $5.

We have a question: In Mariam's neighborhood, there are 40 houses on one side of the main road passing through the neighborhood and three times as many homes on the other side of the road. How many homes are in Mariam's neighborhood?
And an answer: 160
So how you got the answer?
If the number of homes on one side of the main road is three times the number on the other side, there are 3 * 40 = 120 homes. In total, there are 40 + 120 = 160 homes in Mariam's neighborhood.

We have a question: Tim gets 6 hours of sleep 2 days in a row. To make up for it he sleeps 10 hours the next 2 days. How much sleep did he get?
And an answer: 32
So how you got the answer?
He got 2 * 6 = 12 hours the first 2 days. The next 2 days he gets 2 * 10 = 20 hours. So he got 12 + 20 = 32 hours.
