Answer:
y= cost of a popcorn
x= cost of a drink
3x+2y=45
9x+3y=110.25
y= 8.25
x= 9.5
popcorn= $8.25
drink= $9.50
Step-by-step explanation:

Answer:
The smallest sample size to satisfy the conditions is n=500.
Step-by-step explanation:
The condition for performing the inference related to the sample size is that, for all the categories, the expected success and failures in the sample are at least 10:

The largest sample size required will be for the minimum p or (1-p).
This happens to be the proportion that can play other instruments: 2%.
Then, we can calculate the minimum sample size as:
