An orchestra will give a concert. There are 1,500 seats in the concert hall. Some tickets have been sold. How many tickets remain?

Given: tickets sold (IV), x

tickets remain (DV), y

Which equation best describes this situation?

An orchestra will give a concert. There are 1,500 seats in the concert hall. Some tickets have been sold. How many tickets remain?

Using the equation y = 1500 - x

If given the amount of tickets sold, where in the equation would we plug it in?
