Find the cost of this trip: find the airfare for flying round trip from denver to detroit if a one-way ticket is $235.00, there is no discount, and the sales tax is 5% of the total cost.

493.50

Step-by-step explanation:

One Way Cost = $235.00

Both ways = 2 * 235 = 470

Now is the time to add the tax. You only pay a tax when goods or services have been exchanged. So the return ticket and the one way are when you pay.

Sales Tax = 470 * 5/100 = 23.50

The total ticket cost = cost + sales tax = 470 + 23.50 = 493.50  

You can do this in one step

Recognize that the total amount is 105% or 1.05 * Cost of the ticket.

1.05 * 470 = 493.50 just as it was before. Doing it the long way might be easier to understand but eventually you should  shorten the process.
