Two friends, Alejandro and Mia, agreed to split the check at a restaurant. Alejandro ordered \$12 worth of food and Mia ordered \$18 worth. At the end of the meal, Alejandro put his \$12 contribution on the table, plus a 20% tip on his bill and Mia put her \$18 contribution on the table, plus a 15% tip on her bill. The total tip left by Alejandro and Mia is equal to r% of the total check for their table, where the "total check" amount does not include the tip. What is r?

Alejandro's tip =\$12 x 20% =\$2.40

Mia's tip =\$18 x 15% =\$2.70

\$2.40 + \$2.70 = \$5.10 Total amount of tips.

\$12 + \$18 =\$30 Total food bill without the tips

r = \$5.10 / \$30 =0.17 x 100 = 17% Tips as a percentage of their food bill.
