The library needs at least 15 people to sign up for an event in order to run it. Currently, 3 people have signed up, and the library expects 2 more pe
ople to sign up today. How many more people does the library need to sign up in order to meet the minimum requirement?
To find out how many more people are needed, we need to subtract the number of people who have already signed up from the minimum requirement.
The minimum requirement is 15 people.
The number of people who have already signed up is 3.
Therefore, we need to subtract 3 from 15: 15 - 3 = 12.
The library needs 12 more people to sign up in order to meet the minimum requirement.
