Answer:
68
Step-by-step explanation:
Let x=adult tickets and y=child tickets
1) 15x+11y=1889
2) x+y=147
multiply equation 1 by -1/11 on both sides to get:
-(15/11)x-y=-171.73
add new equation with equation 2 to get
-4/11x=-24.73
Isolate x to get:
x=67.99999
Round up to get 68 adult tickets
Multiply out the brackets:
4x - 1/4 > 12 - 2x
Add 2x to both sides:
6x - 1/4 > 12
Add 1/4 to both sides:
6x > 12 1/4
Divide both sides by 6:
x > 2.04
Change to a fraction form, therefore the answer is B
