#### Work Step by Step

First, it is important to note that the bus makes 20 round trips daily, but the fare is charged for one way. In other words if you actually took a round trip (airport to beach and back to airport), you would pay 11 dollars to go from airport to beach and another 11 dollars to go back to the airport.
There are 20 round trips per day. The bus holds 32 people. The 20 round trips equates to 20 trips to the beach and 20 trips to the airport —a total of 40 one way trips.
Then we can take 32 people each way. So 40 x 32 gives us 1,280 total passengers in a day. Each passenger pays 11 dollars. So 1280 x 11 gives us 14,080 dollars per day
