Stella makes 2% royalties on a book she wrote. How much money did her book earn in sales last year if she made $53,000 in royalties?

Answer:

#S=($53000)/.02=$2,650,000#

Explanation:

We can take the book sales (#S#), multiply it by the royalty percentage (#%#), and see how much she makes in royalties (#R#):

#S xx % = R#

Now let's substitute in what we know:

#S xx 2% = $53,000#

To find #S# (book sales) we now divide both sides by 2% (which is the same as 0.02):

#S=($53000)/.02=$2,650,000#
