You take your friend out to dinner for their birthday. The bill was $65.00. You left $75.00 which includes the tip. What was the percentage of the tip? (hint divide the tip amount by the amount of the dinner) (use a % sign in your answer and round to one decimal place)
All i did was subtract 65 from the 75 which gave me 10 and I divided that by the original cost which was 65. That gave me 6.5%. Another possible answer is 0.1538461538461538. I just tried my best.
