The pressure exerted on the floor by a person's shoe heel depends on the person and the width of the heel. The formula is

$$P=\frac{1.2W}{H^2}$$

where P is the pressure in pounds per square inch. W is the weight in pounds, and H is heel width in inches. Which of the following shows the pressure formula solved for H?

Which inequality is represented by the graph below?
