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 except 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)

Let x represent the number of days.

3 + 2x ≥ 15

To solve this problem, we can set up an inequality. Let's use the variable "d" to represent the number of days.

The number of people signed up can be represented by the expression 3 + 2d, where d is the number of days.

The library needs at least 15 people to sign up, so the inequality can be written as:

3 + 2d ≥ 15

This inequality states that the number of people signed up (3 + 2d) must be greater than or equal to 15.

To find out after how many days the library will be sure it can run the event, we need to solve this inequality.

Let's assume that the number of days required for the library to be sure it can run the event is represented by the variable "d".

The number of people who have signed up after "d" days can be represented by the expression "3 + 2d".

The library needs at least 15 people to sign up for the event. Thus, the inequality that could be used to solve this problem is:

3 + 2d ≥ 15
