Answer:
D.7,722
Step-by-step explanation:
We have been given that a 6-car monorail train can carry 78 people. The train makes 99 trips during the day. We are asked to find the greatest number of people the train can carry in one day.
The greatest number of people the train can carry in one day will be equal to number of trips times the total number of people that train can carry in each trip.
[tex]\text{The greatest number of people the train can carry in one day}=78\times 99[/tex]
[tex]\text{The greatest number of people the train can carry in one day}=7722[/tex]
Therefore, the train can carry at-most 7722 people in one day.
