the charge for a single room at hotel p is 50 percent less than the charge for a single room at hotel r and 10 percent less than the charge for a single room at hotel g . the charge for a single room at hotel r is what percent greater than the charge for a single room at hotel g ?
p = 0.5 r = 0.9 g r = 0.9 g / 0.5 = 1.8 * g thus r is 80 % greater than g . the answer is d .
multiply(divide(subtract(const_100, multiply(divide(subtract(const_100, 50), subtract(const_100, 10)), const_100)), multiply(divide(subtract(const_100, 50), subtract(const_100, 10)), const_100)), const_100)
