I come up with a different answer for the first question.
You start with 32 pairs. The first contest has 16 matches which yield 16 winners. The second match has 8 matches which yield 8 winners. Keep this pattern going to see if your answer is right.
You could interpret the second question in the way you did. Each golfer played at least one match. However, the question may be asking how many total matches there were before a winner was declared.
I am confused .. with 64 golfers forming pairs which equal 32, and each pair plays a match, wouldn't that be 32 matches to start with, concluding with 16 winners? ... and that set would form new partners, which would make 8 pairs ending with 4 winners, down to 2 pair with 1 winner ... what am I doing wrong? thank you for your help.
You're right, Emily. I goofed on my original figures. There were 5 matches to determine a winner.
1st match -- 32 pairs, 16 matches and 16 winners
2nd match -- 16 pairs, 8 matches and 8 winners
3rd match -- 8 pairs, 4 matches and 4 winners
4th match -- 4 pairs, 4 matches and 2 winners
5th match -- 2 pairs, 1 match and 1 winner
Thanks for catching my mistake. That's why it's always a good idea to make sure you understand an answer, no matter who tells you differently.
WoW ... You made my day! ... Thank you .. this one gets copied and printed for mom :-) .. (i keep telling her this is not 4th grade math! lol! but she likes to keep me thinking) thanks again, it is great to have people that help us! ... have a great day!

The main point, Emily, is that YOU were able to do it. Not only that, but you were confident enough to challenge my answer. And you were right! :-)
