Given the Float variables: Charge = −87.23 and Cost = 456.87

a. Val(Str(Cost),N)

b. Abs(Round(Charge))  Refer to Example 9.15. Add the following functionality to this program: Allow the user to enter the cost of a gallon of gas on each trip and use a function, Cost() to calculate the cost of purchasing gas for that trip. Display this information in the table with the rest of the information. You will need to add another parallel array, Trip Cost, to hold this information.
