Question

Patty ordered a pizza to be delivered. The bill was $12.00. Patty pays $15 and tells the delivery person to keep the change as a tip. What percent tip did she give?

Answer 1

Since you know Patty gave a tip of $3, it’s pretty easy to understand that 3 is 1/4 of 12.00 (the pizza price), resulting in a tip percentage of 24%

Answer 2

25%
(15-12)/12=1/4....
