You just went on a blind date and wanted to impress the girl by adding an 18% tip to the total cost of the meal. Two entrees came to a total of $35.90. Desserts cost $7.50 and beverages cost $6.60. What is the 18% tip going to cost?
Add all the courses to get the total cost of the meal:
Total cost = $35.90 + $7.50 + $6.60 = $50.00
Get 18% of the total, to compute the tip to be paid:
$50(18%) = $50(.18) = $9.00
