A pilot takes a taxi from the airport to a hotel. The taxi drivers charges a $2.50 initial charge plus $2.65 per mile. Which equation can be used to find y, the total cost of the trip, if x represents the number of miles of the trip?

• y = 2.50x + 2.65

• y = 2.65x - 2.50

• y = 2.65x + 2.50

• y = 2.65(x + 2.50)

A fish is swimming at a constant rate towards the ocean floor. The equation y = -7x -3 can be used to represent this situation, where y is the depth of the fish in meters below sea level and x is the number of seconds the fish has been swimming.

Which statement best describes the depth of the fish given this equation?

• From a starting position of 7 meters below sea level, the fish is descending 3 meters per second.

• From a starting position of 7 meters below sea level, the fish is ascending 3 meters per second.

• From a starting position of 3 meters below sea level, the fish is descending 7 meters per second.

• From a starting position of 3 meters below sea level, the fish is ascending 7 meters per second

Nicholas is buying shirts for his baseball team. He will pay $9.50 for each shirt plus a one time fee of $22.50 for the design.

Which equation can be used to find y, the total cost to buy x shirts?

• y = 9.50x + 22.50

• y = 22.50x + 9.50

• y = 9.50x - 22.50

• y = 22.50x - 9.50
