First you do 3 to the 2nd power which is 9 then you just add 12+9+50= 71
a+y≤1000 and 25a+12.50y>15000 is the system of inequalities that could be used to solve the problem.
Step-by-step explanation:
Given,
Price of one adult ticket = a = $25
Price of one youth ticket = y = $12.50
Maximum people that can be hold by theater = 1000
Therefore;
The maximum number of people can be 1000 or less than that.

As they want to revenue to be more than 15,000 therefore,

a+y≤1000 and 25a+12.50y>15000 is the system of inequalities that could be used to solve the problem.
