Two friends, Alejandra and Mia, agreed to split the check at a restaurant. Alejandra ordered $12 worth of food and Mia ordered $18 worth. At the end of the meal, Alejandra put her $12 contribution on the table, plus a 20% tip and Mia put her $18 contribution on the table, plus a 15% tip. The total tip left by Alejandra 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?

Respuesta :

AJ135
the total check is $30.
Alejandra's tip is 20% of 12 which is $2.40
Mia's tip is 15% of 18 which is $1.80
1.8 + 2.4 = $4.20
4.20/30 = 0.14
0.14 x 100 = 14%
r  =  14

Answer:

17
