• Account X and Account Y will have the same balance because both earn the same interest rate.

• Account Y will have a larger balance because an account that is earning compounded annual interest will earn more money than an account with simple annual interest with the same rates.

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

• y = 2.50x + 2.65

• y = 2.65(x + 2.50)

• y = 2.65x - 2.50

• y = 2.65x + 2.50
