$2\mathrm{.}26$ 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 $=\frac{(\text{A}\text{g}\text{e}0\mathrm{.}2757+\text{W}\text{e}\text{i}\text{g}\text{h}\text{t}0\mathrm{.}03295+\text{H}\text{e}\text{a}\text{r}\text{t}\text{R}\text{a}\text{t}\text{e}1\mathrm{.}0781-75\mathrm{.}4991)\text{T}\text{i}\text{m}\text{e}}{8\mathrm{.}368}$

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:

$49155148,60$

the output is:

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