Mr. Sanchez bought 6 - 4 = 2 feet of rope. He bought a total of 6 + 2 = 8 feet of rope. In inches, this is equal to 8 x 12 = 96.
The answer: 96
Reverse engineering the question: Last week, Mr. Sanchez bought 6 feet of rope for their class activity. He found that he lacks rope for the activity so this week, he bought 4 feet less than last week. Since there are 12 inches in a foot, how many inches of ribbon did Mr. Sanchez buy in all?


Reasoning and answer: There are 144 / 12 = 12 sets of 12 cans that the family collected. So, the family would receive $0.50 x 12 = $6 for the cans. There are 20 / 5 = 4 sets of 5 kilograms of newspapers that the family collected. So, the family would receive $1.50 x 4 = $6 for the newspapers. Therefore, the family would receive a total of $6 + $6 = $12.
The answer: 12
What was the question?
Question: For every 12 cans you recycle, you receive $0.50, and for every 5 kilograms of newspapers, you receive $1.50. If your family collected 144 cans and 20 kilograms of newspapers, how much money would you receive?


The chickens had 7 * 2 = 14 legs. The sheep had 5 * 4 = 20 legs. There were 14 + 20 = 34 legs.

Reasoning and answer: With a garden hose that fills at a rate of 1.6 gallons per minute, and a hole that leaks at 0.1 gallons per minute, the net fill rate becomes 1.6 - 0.1 = 1.5 gallons per minute. Therefore, to fill a 60 - gallon pool, it will take 60 / 1.5 = 40 minutes.
The answer: 40
