Multiple Choice

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?

• y = 1500x

• y = 1500 - x

• y = x + 1500

• $$y=\frac{x}{1500}$$  

Multiple Choice

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?

• y

• x

• replace 1500 with the amount of tickets sold.
