Answer 1

c.

Explanation:

first equation: youre looking for amount of tickets. if you add the amount of student tickets with the amount of adult tickets, you get the total amount of tickets, 75.

second equation: youre looking for prices here. if you multiply the amount of student tickets with the price of student tickets, and add that to the amount of adult tickets multiplied with the price of adult tickets, you get the total price for all tickets sold.
