Answer

The final answer is 34 strokes.

Work Step by Step

First, we are given that the par for all nine holes is 36. We add up the first four holes and subtract it from 36 to see the remaining par for the remaining 5 holes. To add up the first four holes' par, we do: 4+4+3+5 = 8+8 = 16. Then we subtract it from 36 to get, 36-16 = 20. So there is a par of 20 remaining for the last 5 holes. Since there are 5 holes left, we want to see how much each hole's par should be. To do this, we divide 20/5 = 4. So each hole has a score of 4 par. Now, the problem gives us the golfer's score for each of the last 5 holes. If he has a score of 0, that means he had 4 strokes (because he was par, so 4+0=4). If he has a score of +1, that means he has 5 strokes (because he was 1 over par, so 1+4=5). If he has a score of -1, that means he has 3 strokes (because he was 1 under par, so 4+(-1) = 4-1 = 3). The golfer had 2 scores of -1, 2 scores of 0, and 1 score of 1. This means he had two 3 strokes, two 4 strokes, and one 5 stroke. Adding this to our previous strokes given in the chart, we get 6+3+3+3 (our original strokes) + 3 + 3 + 4 + 4 + 5. This gives us a total of 15 + 19 = 34 strokes. So the golfer had 34 strokes total.
