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 people to sign up each day. After how many days will the library be sure it can run the event? Write an inequality that could be used to solve this problem.(1 point)

Answer 1

The correct inequality to use for this problem is:

2d + 3 ≥ 15, where d is the number of days.

This reflects that the total number of people signed up (which starts at 3 and increases by 2 each day) needs to be at least 15 in order for the event to be held.
