Answer:
0.105
Step-by-step explanation:
0.25/100 x 42 = 0.105
2c+3d=900
C=x
D=350-x
2x+3 (350-x)=900
Solve for x to get number of children
attended the fair that day
2x+1050-3x=900
2x-3x=900-1050
-1 x=-150
x=150 children
350-150=200 adult
The answer would be 408 if u take 340 and divide it by 10, then you get 34 and times it by 12
