## Introductory Algebra for College Students (7th Edition)

Let's translate these words into mathematical language. We are trying to look for the unknown number, $x$. 48 = 30%$\times x$ We change 30% into a decimal by changing the % symbol into a decimal and moving that decimal two places to the left. We then get: 48 = 0.30$\times x$ Now we can solve for $x$. We divide each side by 0.30, and we get: $x = 160$
