Step-by-step explanation:
I've written the answer and steps to solve the question a piece of paper which is in the attached photo. Hope this helps!
The number of advance tickets sold is 25 and same day tickets sold is 30.
Data Given;
- Advance Ticket = $30
- Same-day Ticket = $25
- Total Ticket = $60
- Total Cost of Ticket = $1625
<h3>System of Equations</h3>
Let the number of advance ticket be represented by x
Let the number of same-day ticket be represented by y

From the system of equations above, we can easily pick any to start our calculation.
Using equation (i),
x + y = 60
x = 60 - y ...equation(iii)
Put equation (iii) into equation (ii)

Put the value of y into equation (i)

From the calculation above, the number of advance tickets sold is 25 and same-day tickets is 30.
