164 kids

165 adults

step-by-step explanation:

first you need to make two equations

kids = x

adults = y

first equation = x+y=329

second equation = 1.5x + 4y = 906

solve by substitution

x = 329 - y

1.5 (329 - y) + 4 y = 906

493.5 - 1.5y + 4y = 906

combine like terms

2.5y = 412.5

y = 165

plug back into one of the equations

x + 165 = 329

x = 164
