Driving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon (both floats) as input, and output the gas cost for 10 miles, 50 miles, and 400 miles.

Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print('%0.2f %0.2f %0.2f' % (your_value1, your_value2, your_value3))

Ex: If the input is:

20.0 3.1599 

Then the output is:

1.58 7.90 63.20 

Note: Real per-mile cost would also include maintenance and depreciation.
