Answer 3

Rewrite it in math terms:
$$\underbrace{4+}_\text{four more than}\,\underbrace{3n}_\text{three times a number}\,\underbrace{<30}_\text{is less than 30}\implies4+3n<30$$Can you isolate and solve for \(n\)?

Answer 4

$$4+3n<30\\3n<30-4=26\text{ by subtracting 4 from both sides}\\n<\frac{26}3\approx8.67\text{ by dividing both sides by 3}$$
