Implement a function computeTotal$()$ that requests an decimal value representing a price and an integer representing a quantity from the user. If both numbers are positive $($not negative and not zero$),$ the function should print the price times the quantity using a dollar sign appropriately. If either value is negative or zero, the program should not do anything.

$g=\frac{GM}{R^2}$

Where $G$ is the gravitational constant $($approximately $6\mathrm{.}674{10}^{-11}\frac{m^3}{k}\frac{g}{s^2}),M$ is the mass of the planet, and $R$ is its radius $($in meters!!$).$ Display the calculated surface gravity.
