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

Write a function 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. The function called with arguments $(20\mathrm{.}0,3\mathrm{.}1599,50\mathrm{.}0)$ returns $7\mathrm{.}89975.$

Define that function in a program whose inputs are the car's miles per gallon and the price of gas in dollars per gallon $($both float$).$ Output

the gas cost for $10$ miles, $50$ miles, and $400$ miles, by calling your driving$\_$cost function three times.

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$\}\text{'})$

Ex: If the input is:

$20\mathrm{.}0$

$3\mathrm{.}1599$

the output is:

$1\mathrm{.}58$

$7\mathrm{.}90$

$63\mathrm{.}20$

Your program must define and call a function:

def driving$\_$cost$($miles$\_$per$\_$gallon, dollars$\_$per$\_$gallon, miles$\_$driven$)$

$545890\mathrm{.}2208334.$qx$3$zqy$7$
