The number of advance tickets sold is 25 and same day tickets sold is 30.
Data Given;
Let the number of advance ticket be represented by x
Let the number of same-day ticket be represented by y
[tex]x + y = 60\\ 30x + 25y = 1625[/tex]
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)
[tex]30x + 25y = 1625\\ x = 60 - y\\ 30(60 - y) + 25y = 1625\\ 1800 - 30y + 25y = 1625\\ 1800 -5y = 1625\\ 5y = 1800 - 1625\\ 5y = 175\\ 5y/5 = 175/5\\ y = 35[/tex]
Put the value of y into equation (i)
[tex]x+y = 60\\ x + 35 = 60\\ x = 60 - 35\\ x = 25[/tex]
From the calculation above, the number of advance tickets sold is 25 and same-day tickets is 30.
