The cost of buying x movie tickets, which cost $16 each, is represented by the equation y = 16x.
The cost, y, of buying x movie tickets, when each ticket costs $16, can be represented by a simple linear equation. This equation can be set up by multiplying the number of tickets, x, by the cost per ticket. Therefore, the equation which represents the cost of the movie tickets is:
y = 16x
This equation indicates that if you buy x movie tickets, you would multiply x by 16 to get your total cost, y.
