# 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? ##### 1 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
