Problem of the week!

My algebra classes have been working on positive and negative integers. This weekend I went mini-golfing and was inspired to do a little integer math with the score card. Answer these questions correct to earn some extra credit! 

1. What was my average score?

2. What was Mike's average score?

3. How many points above or below the adult par did I score?

4. How many points above or below the child's par did Mike score?

5. What was the difference of our scores mid-game?

6. For how many holes was I at exactly +5 above par?

7. How many holes did Mike score -2 below the child's par?

8. Who was the better golfer? :-)
