Given Data:
1 cm= 20 miles.
Car travels 35 miles/gallon.
Cost of gas= $ 3.10/gallon.
Total trip measures =32.5 cm.
The distance travelled by the car can be determined as,
![\begin{gathered} d=32.5\operatorname{cm}*\frac{20\text{ miles}}{1\text{ cm}} \\ =650\text{ miles.} \end{gathered}]()
The amount of gas used during travel can be determined as,

The cost of the trip can be determined as,

Thus, the cost of the trip is $ 57.57.
