You can put this solution on YOUR website!
Let +m+ = miles driven
Let +d+ = number of days car is used
Let C = cost of rental in dollars
The formula is:
+C+=+24d+%2B+.17m+
-------------------
given:
+C+=+52.9+
+d+=1+
------------
+52.9+=+24%2A1+%2B+.17m+
+.17m+=+52.9+-+24+
+.17m+=+28.9+
+m+=+170+
She drove 170 miles
