Answer

On Saturday, let female be 100u , then male will be 100u + 130

ON Sunday, male decrease by 20% and female increase by 20%
Sunday male = (100u + 130) x 0.8 = 80u + 104
Sunday female = 100u x 1.2 = 120u

On Sunday total participant, 574 = 80u + 104 + 120u
574 = 200u + 104
u = 2.35

On Saturday, total participant = 100u + 130 + 100u = 600

Total money paid on both days = (600+574) X 25 = $29350 ###
