The charge for a single room at Hotel R is what percent greater than the charge for a single room at Hotel G ?	Choose the correct option:	A) 15%	B) 20%	C) 40%	D) 50%	E) 150%
Let rate in R = 100x   then P = 75x   G = 100y   P = 90y   Thus   75 x=90y   or x = 1.20 y   Ans R = 120y   so increase = 20%   Answer: 20%.
