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.

e) none of the above because the measure of angle cba is 101°
