comment Getting percentage difference between two numbers?
x = 100*5000/80000 = 500000/80000 = 50/8 = 6.25

That is a raise of $5000 per $80000. Percent means per hundred, so to convert that to a percent, we just solve x/100 = 5000/80000 for x.

comment How is the set of all programs countable?
@Jay That is not true for arbitrary real numbers. $\pi$ is computable, as is any real number that you can describe by an algorithm, but most real numbers are not computable.
