Question 890882: How many different tips could you leave in a restaurant if you had a quarter, a half-dollar, a dollar, 5-dollar bill, and a 10 dollar bill?
I think the answer is 32 ways, since there are 5 different payment choices, and you can either leave the tip, or not leave the tip, which makes it 2 for choosing either to leave or not, so then the answer is 2 to the power of 5, which is 2^5 = 32. Am I correct?
Thank You!
