Iliada went to Minewaska state park one day this summer. All of the people at the park were either either hiking or bike riding. There are 178 more hikers than bike riders. If there were a total of 676 people at the park, how many was hiking and how many were riding their bikes?
b r = 178 + h; b r + h = 676; then, 178 + 2h = 676 => h = 498/2 = 249 => b r = 178 + 249 = 427;
