[Question]: The population of Delaware is 974,000. A study showed that there are 673 cell phones per 1000 people in the state. How many cell phones are there in Delaware?
[Answer]: There are 974000 / 1000 = 974 groups of 1000 people in the state. These groups will have 974 * 673 = 655502 cell phones.
So the answer is 655502.

[Question]: Jerry is refilling the duck pond in his backyard during a drought. The pond can hold 200 gallons of water. Jerry's hose can normally pump 6 gallons/minute, but due to drought restrictions, it can only pump 2/3rds as fast right now. How many minutes will it take Jerry to fill his pond?
[Answer]: First find the current rate the hose pumps by multiplying its normal rate by 2 / 3: 6 gallons / minute * 2 / 3 = 4 gallons / minute. Then divide the number of gallons in the pond by the number of gallons pumped each minute to find how many minutes filling the pond takes: 200 gallons / 4 gallons / minute = 50 minutes.
So the answer is 50.

[Question]: Johnny is a dog walker. He can walk 3 dogs at once. He gets paid $15 for a 30-minute walk and $20 for a 60-minute walk. Johnny works for 4 hours per day. If he always walks the maximum number of dogs possible and 6 dogs have 60-minute walks per day, how much money does he make in a week where he works 5 days?
[Answer]:
Johnny spends 6 / 3 = 2 hours walking the 6 dogs who have 60 - minute walks. He makes $20 * 6 = $120 for these walks. Thus, he has 4 - 2 = 2 hours = 120 minutes left to walk the other dogs. He can walk 3 * (120 / 30) = 12 dogs in this time. Thus, he will make $15 * 12 = $180 on these walks. In total per day, he makes $120 + $180 = $300 per day. Thus, during the week, he makes $300 * 5 = $1500.
So the answer is 1500.
