Need help with this serious problem in mathematics and was driving me crazy.?

At one time Texas Junior College Teachers annual Association conference was held in Austin. At this time charges in Austin is $ 1.35 for first 1 / 5 miles and $ 0.30 for each additional 1 / 5 mile. If the distance one of the Convention hotels to the airport is 8.5 miles, how many charges from hotel to airport? (Round to nearest cent more press). ++++++++++++++++++++++++++++++++++++++++++ Well, this is the way works as follows: 1.35 for the first 1 / 5 miles. Converts (1 / 5 do so to 0.2) 8.5 miles divided by 0.2 = 42.5 fifth .. 30 (42.5) = 12.75 + 1.35 (first 1 / 5 miles) = 14.10 for the trip to the airport. Computer tells me I'm wrong. What am I doing wrong?

1.35 + (8.5-1 / 5) * 5 *. 3 = 1.35 8.3 * 5 *. 3 = 1.35 2.49 = 1.35 12.45 = 13.80've added 1.35 for the first fifth of a mile, but still including the first through fifth, multiplied by .3. Whereas, should be multiplied 41.5 .3 instead of multiplying 42.5 .3.
