Program $1$ Basic: Gasoline

Goal:

In this program, you will convert gallons of gasoline into several other measures. For this, we will use the

following conversions:

$1$ gallon $=3\mathrm{.}78541$ liters

$1$ barrel of oil produces approximately $19\mathrm{.}5$ gallons of gasoline

FYI: That one barrel of oil is equivalent to $42$ gallons

$1$ gallon of gasoline produces approximately $20$ pounds of $CO2$ when burned

$1$ gallon of gasoline produces approximately $115,000$BTU, while $1$ gallon of ethanol produces

approximately $75,700$ BTU

HINT: Set up a proportion to figure out how many gallons of ethanol is equivalent to $1$

gallon of gasoline

$1$ gallon of gasoline costs $$2\mathrm{.}90$

Specifications:

Ask the user "How many gallons of gasoline?" and accept the input as a float

Output the results of the conversions with the specified precision:

How many liters of gasoline this represents $(3$ decimal places$)$

How many barrels of oil are required to produce the gasoline $(3$ decimal places$)$

How many pounds of $CO2$ the gasoline produces when burned $(3$ decimal places$)$

How many gallons of ethanol is energy equivalent to the gasoline $(2$ decimal places$)$

How much the gasoline will cost at the pump $(2$ decimal places$)$
