Answer the following question.
Donna is catering for a party. She makes 20 sandwiches and then cuts them in half, before cutting them in half again. She then gives everyone 8 portions. How many people can she feed?
Step-by-step reasoning process: First, we need to determine the overall number of portions. To do this, we begin by performing 20 * 2 = 40 portions after the first halving. Next, we take this portion number and double it again, performing 40 * 2 = 80 portions after the second halving. Lastly, we divide this portion number by the number of portions each person will be served, performing 80 / 8 = 10 people served.
The answer is 10.

Answer the following question.
Tenisha had 40 dogs that she kept at home as pets. If 60% of them are female, and 3/4 of the female gives birth to 10 puppies each, calculate the total number of puppies that Tenisha remains with after donating 130 puppies to the church.
Step-by-step reasoning process: If Tenisha has 40 dogs, the number of female dogs is 60 / 100 * 40 = 24. 3 / 4 of the females give birth, meaning 3 / 4 * 24 = 18 female dogs gives birth to puppies. Since each dog that gave birth had 10 puppies, the number of puppies that were born is 18 * 10 = 180. After donating 130 puppies to the church, Tenisha remained with 180 - 130 = 50 puppies.
The answer is 50.

Answer the following question.
Jeff’s swimming coach required him to swim 98 laps over the weekend. On Saturday, Jeff swam 27 laps. On Sunday morning, he swam 15 laps, took a break, then resumed practice in the afternoon. How many laps did Jeff have remaining when he took the break?
Step-by-step reasoning process: After Jeff swam on Saturday, there remained 98 - 27 = 71 laps. After Sunday morning’s 15 laps there remained 71 - 15 = 56 laps. Therefore, when Jeff took the break, he had 56 laps remaining.

Answer the following question.
Mark wants to set the record for most consecutive ropes jumped. The record is 54,000. He can jump 3 times a second. How many hours would he need to jump rope?
Step-by-step reasoning process: He can jump 3 * 60 = 180 times per minute. So he can jump 180 * 60 = 10,800 per hour. So it would take him 54,000 / 10,800 = 5 hours.
The answer is 5.
