Hi there!
3(x - 2) < 18
Begin by dividing both sides by 3:
3(x - 2)/3 < 18/3
x - 2 < 6
Add 2 to both sides:
x - 2 + 2 < 6 + 2
x < 8
85% liked => 15% didn't like
30 = 15% of x
30 = 0.15 x => x = 30 / 0.15 = 200. This is the total number of students at the library.
Then 200 - 30 = 170 is the number of students whom did like reading mistery stories.
Answer: 170.
