Choose the correct answer:  A) 60  B) 90  C) 120  D) 150  E) 240
Let x be the number of timeshare condos available at Playa del Mar.   Then number of timeshare condos available at Sunset Beach = 3/5x   We know, x + 2/5 x = 350   Hence, x = 250. So, number of timeshare condos available at Playa del Mar = 250   the difference between the number of condos available at Sunset Beach and the number of condos available at Playa del Mar = x - 2/5x = 3/5x = 3/5(250) = 150   The correct answer is 150
