Define a function named DrivingCost with parameters drivenMiles, milesPerGallon, and dollarsPerGallon, that returns the dollar cost to drive those miles. All items are of type float.

Ex: If the function is called with:

$5020\mathrm{.}03\mathrm{.}1599$

the function returns:

$7\mathrm{.}89975$

Write a main program whose inputs are the car's miles$/$gallon and the gas dollars$/$gallon $($both floats$).$ Output the gas cost for $10$ miles, $50$ miles, and $400$ miles, by calling function DrivingCost$()$ three times.

Output the cost with two digits after the decimal point, which can be achieved as follows:

Put cost to output with $2$ decimal places

Ex: If the input is:

$20\mathrm{.}03\mathrm{.}1599$

the output is:

$1\mathrm{.}587\mathrm{.}9063\mathrm{.}20$
