Part A: To find out how many cable cars will be filled, you divide the total number of people by the capacity of each cable car.
Number of cable cars filled = Total people / Capacity of each cable car
Number of cable cars filled = 51 / 6 = 8.5
Since you can't have half a cable car, you can fill 8 cable cars completely with a few people left over.
Answer for Part A: 8 cable cars
Part B: To find how many more people are needed to fill the next cable car, you can determine how many people are left after filling 8 cable cars.
People in 8 cable cars = 8 * 6 = 48 people
People left in line = 51 - 48 = 3 people
A cable car is needed to hold 6 people, so you subtract the number of people already in line from the capacity of the next cable car:
People needed to fill the next cable car = 6 - 3 = 3 people
Answer for Part B: 3 people
