Cameron is playing 9 holes of golf. he needs to score a total of at most 10 over par on the last four holes to beat his best golf score. on the last four holes, he scores 5 over par, 3 under par, 6 over par, and 3 under par. part 1 out of 3 enter and find the value of an expression that gives cameron's score for 4 holes of golf. what is the expression and what is his score

To find the expression, take the numbers over par as positives and the numbers under pair as negatives, so you can write this expression:

15 + (-3) + 6 + (-3) =

That is the expression.

To find the result you group the positives and group the negatives:

Positives: 15 + 6 = 21

Negatives: 3 + 3 = 6

Now subtract the total negative from the total positive

21 - 6 = 15.

So, he got 15 over par in the last four holes.

Given that he need at most 10 you know he couldn't beat his best score.

He score 15 - 10 = 5 over what he needed.

The answer would be 54.2%.
