Let x be the number of days since the initial 3 people signed up.
The total number of people signed up after x days is given by the expression 3 + 2x.
The inequality that represents the condition for the library to be sure it can run the event is: 3 + 2x ≥ 15.
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
