The large van has 23 seats and the small van has 17 seats
B: 914-20(27.80)=X, multiply: 20(27.80)=556, 914-556=$358 :A.
C: 914-27.80=$886.20 :)
I don't know where the angle β is, so I will make the assumption that tanβ = h/r

V volume = 60
r radius = 2
h = r tanβ
First compute the coefficient like this:

Simplifying the fraction over 4! we get:

and the variables are

. So answer

.
The correct answer is C then.
