He can only pick 7 different groups because 2 times 7 is 14, and there are 15 people in all.

Hope this helps. c:

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%.
