A group of 78 students and 10 teachers go to the zoo. All the students and teachers ride a train through the zoo to see the
animals.
• The train can hold a maximum of 25 people.
• At least 4 adults must ride with each group of students
on the train.
Part A
What is the fewest number of trips the train will take so that
everyone gets to ride?

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212
