Look at the gradient of both the equations (the x multiplier, usually known as m), and there are a couple of rules:
Parallel: The gradients are identical
Perpendicular: Look at the gradients as fractions. To get the perpendicular to a gradient you flip the fraction and change the sign. If this is the case for the two gradients, then they are perpendicular.

Answer:
$50.08
Step-by-step explanation:
Let x be the cheaper hat, is the more expensive hat is 2 times this value, it can be shown by 2x. The addition of these two values = 75.12
x + 2x = 75.12
3x = 75.12
Divide both sides by three to find 1x:
x = 25.04
If the more expensive hat is 2x this, then:
2 * 25.04 = 50.08
So the more expensive hat is $50.08!
