Math, microeconomics or criminal justice
a + c = 925
8a + 6c = 6000
2 equations 2 unknowns
solve by substitution elimination or by matrix algebra
below is the former method
6a + 6c = 6(925) = 5550
8a-6a = 6000-5550
2a = 450
a = 450/2 = 225 adults
c = 925-225= 700 children
8(225)+6(700)
1800 + 4200
= 6000
