Answer:
Children=21 Adult=35
Step-by-step explanation:
[using c for children tickets and a for adult tickets]
56=c+a and 203=3c+4a [starting system of equations]
a=56-c ---> 203=3c+4(56-c) [plugging the first eq. into the second]
203=3c+224-4c [simplify]
-21=-c [simplify 2.0]
c=21 [simplify 3.0]
56=21+a [plugging back into org. eq.]
so a=35
Well, some integers can be irrational, but not all! :)
Step-by-step explanation:
What we are trying to show is the alternative hypothesis. Here, we are trying to show that what the company claims is wrong; less than 80% of the company's customers are under 30.

Answer:
79000
