Question 1058470: Victoria has just flown in from Chicago (and boy are her arms tired!) and needs to get to one of the lovely DFW hotels to relax prior to her psychology conference this weekend. From the airport, she hails a taxi from Reunion Cab that charges a $3.75 fare to get into the cab plus 36 cents for every 2/5 mile the cab driver goes. If Victoria gives $25.00 to the cab driver (which includes a $4.33 tip) once she makes it to the Eastin Hotel. How many EXACT miles did the taxi travel from the airport?

You can put this solution on YOUR website!
cab fare minus tip is
+25+-+4.33+=+20.67+
Let +d+ = distance in miles she traveled
+20.67+-+3.75+=+16.92+
This is what she paid for miles traveled
+%28+.36%2F%282%2F5%29+%29%2Ad+=+16.92+
+.36d%2F.4+=+16.92+
+.9d+=+16.92+
+d+=+18.8+
The taxi traveled 18.8 miles from airport
----------------------
check:
+.36d%2F.4+=+16.92+
+.36%2A18.8%2F.4+=+16.92+
+6.768%2F.4+=+16.92+
+6.768+=+6.768+
OK
