$6\mathrm{.}20$ LAB: Driving costs $-$ functions$-$AS

Write a function called driving$\_$cost$()$ with input parameters miles$\_$per$\_$gallon, dollars$\_$per$\_$gallon, and miles$\_$driven, that returns the dollar cost to drive those miles. All items are of type float. For example, when the function is called with the arguments $(20\mathrm{.}0,3\mathrm{.}1599,50\mathrm{.}0),$ it returns $7\mathrm{.}89975$ to the calling program, which can be used or formatted by the program, appropriately.

Write a program called car$\_$driving$\_$cost$,$ which asks a user for the number of cars to process. It then, for each car, inputs the car's miles per gallon, the price of gas in dollars per gallon, and the number of driven miles $($all in float$).$ The program output the car's miles per gallon, the price of gas in dollars per gallon, the number of driven miles, and the gas price of driving the car. The program calls the function driving$\_$cost$()$ to compute the gas price of driving the car.

Output each floating$-$point value with two digits after the decimal point, which can be achieved as follows:

print$($f$\text{'}\{$your$\_$value:$\mathrm{.}2$f$\}\text{'})$

Example

Enter the number of cars: $2$

for car $1$

Enter miles per gallon: $20$

Enter Dollar amount per gallon: $3\mathrm{.}50$

Enter the number of miles the car was driven: $100$

Miles per gallon: $20\mathrm{.}00$

Dollars per gallon: $$3\mathrm{.}50$

Miles driven: $100\mathrm{.}00$

Driving cost: $$17\mathrm{.}50$

for car $2$

Enter miles per gallon: $15$

Enter Dollar amount per gallon: $3\mathrm{.}99$

Enter the number of miles the car was driven: $112$

Miles per gallon: $15\mathrm{.}00$

Dollars per gallon: $$3\mathrm{.}99$

Miles driven: $112\mathrm{.}00$

Driving cost: $$29\mathrm{.}79$
