An elevator can carry 34 adults or 40 children at one time. During the course of a day, the elevator carries a full passenger load 53 times. If all the passengers were children, how many more people
would the elevator carry than if all the passengers were adults?
If all the passengers were children, the elevator would carry more passengers than if all the
passengers were adults.

The elevator carries 2120 children that day, if all those children were adults instead, the elevator would've carried 1802 adults that day. The question kind of confused me so I'm giving all I can.

B: 8%

Step-by-step explanation:

It asks for percentage of total students, so we add the male and female student totals for a total of 150 students. We also add the numbers of those that are left handed for a total of 12. We divide 12 by 150 (12/150) to get the decimal, 0.08, which is 8%.
