Answer the following question.
How many legs does a spider have if it has two times more than double the number of legs a human has?
Step-by-step reasoning process: Since humans have two legs, we start by finding out what double that amount is by performing 2 * 2 = 4. Spiders have twice that number, so we multiply 4 * 2 to find 8 legs in total.
The answer is 8.

Answer the following question.
Tom is cutting a piece of wood to make a shelf. He cut the wood to 143 cm, but it is too long to fit in the bookshelf he is making. He decides to cut 25 cm off the board. But it turned out longer than the other boards. He had to cut off 7 cm from each to make them the same size. How long were the boards before he cut the 7 cm off?
Step-by-step reasoning process: After the first cut, the board was 143 - 25 = 118 cm. The other boards were 118 + 7 = 125 cm before they got cut.
The answer is 125.

Answer the following question.
Brett has 24 more blue marbles than red marbles. He has 5 times as many blue marbles as red marbles. How many red marbles does he have?

Answer the following question.
Karen is constantly trying to stop the raccoons from getting in her trash. The first lock she tries stalls them for 5 minutes. The next lock stalls them for 3 minutes less than three times as long as the first lock. When Karen tries both locks at once, it stalled the raccoons for five times as long as the second lock alone. How long is that?
Step-by-step reasoning process: First find how long the second lock stalls them: 5 minutes * 3 - 3 minutes = 12 minutes. Then multiply that amount by 5 to find the total time the third lock stall the raccoon: 12 minutes * 5 = 60 minutes.
The answer is 60.
