$2\mathrm{.}26$ LAB: Expression for calories burned during workout

The following equation estimates the average calories burned for a person when exercising, which is based on a scientific journal article $($source$)$:

Calories $=(($Age x $0\mathrm{.}2757)+($Weight x $0\mathrm{.}03295)+($Heart Rate x $1\mathrm{.}0781)75\mathrm{.}4991)$ x Time $/8\mathrm{.}368$

Write a program using inputs age $($years$),$ weight $($pounds$),$ heart rate $($beats per minute$),$ and time $($minutes$),$ respectively. Output the average calories burned for a person.

Output each floating$-$point value with two digits after the decimal point, which can be achieved by executing

cout $<<$ fixed $<<$ setprecision$(2)$; once before all other cout statements.

Ex: If the input is:

$4915514860$

the output is:

Calories: $736\mathrm{.}21$ calories
