Math, microeconomics or criminal justice
B = 3S
B= bikers
S=skateboarders
K= skaters
F = softballers=60
B= 2K
F= 4K
4 equations, 4 unknowns, there should be a unique solution
F=4K=60 softballers
K =60/4 = 15 skaters
B=2K = 2(15) = 30 bikers
B= 3S = 30
S = 10 skateboarders
grand total: 115
S+B+K = 10+30+15 = 55 skateboarders+bikers+skaters
or 115-F= 115-60= 55 S+B+K
Better to die laughing than dying from working this problem.
Better way to go. Although it might take the rest of your natural life to solve this problem, so that would extend your life span much better.
