Solve this problem by writing and solving an inequality. Five more than four times a number is less than 25. What are the possible values of the number?

Let's denote the number as "x".

The inequality can be written as:
4x + 5 < 25

Now, let's solve the inequality:
4x + 5 < 25
Subtract 5 from both sides of the inequality:
4x < 20
Divide both sides of the inequality by 4:
x < 5

Therefore, the number "x" must be less than 5.
