At Gamestop you can buy a Xbox One for $150.00 and each game to go with it would cost $24.00. Or, you can buy a Playstation 4 for $180.00 and each game for $20.00. Write an equation to determine how many games would need to be purchased for the cost to be equal? 

• 150x + 24 = 180 + 20x
• 150 + 24x = 180 + 20x
• 180 - 150 = 24 x + 20x
• 150 - 24x = 180 - 20x

Tank 1 currently has 40 gallons of water and is filling at a rate of 1.5 gallons per minute. Tank 2 has 220 gallons of water and is draining at a rate of 3 gallons per minute. After how many minutes will the two tanks have the same amount of water? Write the equation.

• $40+1.5x=220+3x$
  

• $40x+1.5=220x-3$
  

• $40+1.5x=220-3x$
  

• $1.5x+3x=220+40$
  

A plane travels from New York City to San Francisco with an average speed of 550 mi/h. Another plane leaves from the same airport a half-hour later and travels the same route with an average speed of 625 mi/h. Which equation correctly shows how to solve for the number of hours after the first plane takes off that the second plane catches it?

• 550x = 625x + 30

• 550x = 625(x + 30)

• 550x = 625(x + 0.5)

• 550x = 625x + 0.5
