Step 1By subtracting 72 from each score you get the individual scores above or below par. Then adding the differences up you get the total score above or below par  69  −  72  =  −  3    73  −  72  =  1    70  −  72  =  −  2    74  −  72  =  2    −  3  +  1  −  2  +  2  =  −  2Answer: -2

Step 1First round:the scores are 69, 73, 70, 74so the average is             69      +      73      +      70      +      74        4    =      286    4    =  71.5Second round:The scores have be decreased by 3 for each of the 4 golfers, so their scores are 66, 70, 67, 71So the average is             66      +      70      +      67      +      71        4    =      274    4    =  68.5So, you can see the difference of 3 in the averages of scores of first and second round.So, the accurate answer is 3 strokes below par, was the team score on the first round.
