Given:
The number of people the monorail train can carry per trip = 78
The number of trips during the day = 99
Solution:
The greatest number of people the train can carry in one day equals to the product of the number of people the monorail train can carry per trip with the number of trips during the day.
[tex] The \; greatest \; number \; of \; people \; the \; train \; can \; carry \; in \; one \; day \\ = 78 \times 99 =7722 [/tex]
Conclusion:
The option D) is the correct answer
