In this type of inequality, Simply use the property of addition or subtraction of suitable number on both Left Hand Side & Right Hand Sideto maintain the inequality and also the variable & numbers should be at the different sides in the equation.

Here, the inequality is $-18≤3p$

To solve this, simply dividing $3$to both side of the equation

$\begin{array}{l}−18≤3p\\ \frac{−18}{3}≤\frac{3p}{3}\\ −6≤p\\ pâ‰\yen −6\end{array}$

a. $pâ‰\yen -54$:This is not a correct option because the solution of the inequality is $pâ‰\yen -6$.

b. $-54â‰\yen p$: This is not a correct option because the solution of the inequality is $pâ‰\yen -6$.

c. $pâ‰\yen -6$: This is a correct option because the solution of the inequality is $pâ‰\yen -6$.

d. $-6â‰\yen p$: This is also a correct option because the solution of the inequality is $pâ‰\yen -6$ or $-6â‰\yen p$.
