A pilot takes a taxi from the airport to a hotel. The taxi driver 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=2.65(x + 2.50)

• y=2.65x -2.50

• y = 2.65x + 2.50

The ticket sales for a concert start at 4:00 PM. The table shows the linear relationship between the number of tickets remaining and the number of hours since 4:00 PM. Which function can be used to find y, the number of tickets remaining x hours since 4PM?

• y = 3,000x + 12,000

• y = 3,000x + 15,000

• y = -3000x + 12,000

• y = -3000x + 15,000

Frankie bought a new computer. He made an initial payment of $50 to the store, and he will pay $30 each month until the computer is paid off. Which equation represents the relationship between m, the number of payments Frankie has made, and t, the total amount that Frankie has paid the store?

• t = 50m + 30

• t = 30m - 50

• t = 50m - 30

• t = 30m + 50
