You and a friend buy two fruit smoothies and leave a tip. You split the total and your half comes to $3.60. What percent tip (in decimal form) did you and your friend leave if the fruit smoothies cost $3 each?

Total amount spent = $3.60 x 2 = $7.20

Cost of fruit smoothies = $3 x 2 = $6

tip = $7.20 - $6 = $1.20

% tip x 6/100 = 1.20
% tip x 0.06 = 1.20
% tip = 1.20/0.06 = 20%

In decimal form, % tip = 0.2
