Logan and his friend went out to dinner and spent $18.50.They left a tip of $2.59.
maria [59]
To find this out, use a percent proportion, use cross products, and solve the equation.

\frac{2.59}{18.50}= \frac{p}{100} \\ 18.50p=259 \\  \frac{18.50p}{18.50}= \frac{259}{18.50} \\ p=14

So, the percent tip is 14%.
