Answer the following question.
Frank went to a shop to buy some food for his breakfast. He bought 10 buns for $0.1 each, two bottles of milk, for $2 each, and a carton of eggs, which was three times more expensive than one bottle of milk. How much did Frank pay for his breakfast shopping?
Step-by-step reasoning process: For the buns, Frank paid 10 * 0.1 = $1. He bought two bottles of milk, for $2 each, so he paid for them 2 * 2 = $4. One carton of eggs was three times more expensive than one bottle of milk, so it cost 3 * 2 = $6. So for all his shopping Frank had to pay 1 + 4 + 6 = $11.
The answer is 11.

Answer the following question.
A ship left a port and headed due west, having 400 pounds of food for the journey's supply. After one day of sailing, 2/5 of the supplies had been used by the sailors in the ship. After another two days of sailing, the sailors used 3/5 of the remaining supplies. Calculate the number of supplies remaining in the ship to last the sailors until they dock.
Step-by-step reasoning process: After one day of sailing, 2 / 5 * 400 = 160 pounds of food supplies had been used. The total number of supplies remaining in the ship is 400 - 160 = 240 pounds. After another 2 days of sailing, 3 / 5 * 240 = 144 pounds of food had been used. The total number of supplies remaining in the ship is now 240 - 144 = 96 pounds.
The answer is 96.

Answer the following question.
Harrison Elementary School is overcrowded with 1590 students, so 40% of the students are going to move to a new school. There are 3 grade levels, and each grade level needs one 20-person advanced class and the rest of the students divided evenly into 6 additional classes. How many students will there be in each normal class at the new school?
Step-by-step reasoning process: First find how many students go to the new school: 1590 students * .4 = 636 students. Then divide that number by 3 to find how many students are at each grade level: 636 students / 3 grades = 212 students / grade. Then subtract the 20 students in the gifted class: 212 students - 20 students = 192 students. Then divide that number by 6 to find the number of students in each other class: 192 students / 6 classes = 32 students / class.
The answer is 32.

Answer the following question.
A man intends to complete a journey of 24 km in 8 hours. If he travels at a speed of 4km/hr for the first four hours, at what speed does he need to travel for the remainder of the journey to be right on time?
Step-by-step reasoning process: He covers 4km / hr * 4hrs = 16km in the first 4 hours. He has 24 - 16 = 8km left to cover. He has 8 - 4 = 4 hours to cover the remaining 8km. He has to travel at a speed of 8km / 4hrs = 2km / hr to be right on time.
The answer is 2.
