Best ResponseYou've already chosen the best response.0yup so now we have np>120 we just need to divide when dividing both sides with a negative sign we need to switch the inequality signs

Best ResponseYou've already chosen the best response.0now we need just an n by itself... what can we divide to both sides to make that happen?

Best ResponseYou've already chosen the best response.0yes we divide by p , but remember we want just positive n by itself so we need to divide both sides by p and since we have a negative sign involved, the inequality sign gets switched.

Best ResponseYou've already chosen the best response.0though negative signs in the denominator is frowned upon :( so just place it in the numerator/ \[n < \frac{120}{p}\]
