Inverse variations are of the form x*y = k where k is some fixed number. 

We have x = 9 and y = 2.5 so
x*y = 9*2.5 = 22.5

Therefore, x*y = k updates to x*y = 22.5, implying that k = 22.5

This is why the answer is actually choice B

Side Note: We can solve for y to get y = 22.5/x but this isn't listed as an answer choice

y=20x+14, where:

y is the total amount you would pay for using the sailboat
