A regular dodecahedron is a polyhedron with twelve faces, each of which is a regular pentagon. A space diagonal of the dodecahedron is a line segment which joins two vertices of the dodecahedron which do not lie in the same face. How many space diagonals are there in the dodecahedron?

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
