Multiply 72 (par) times 4 (number of rounds played) = 288
Add 71 + 66 + 67 (scores for rounds played) = 204
Subtract 288 - 204 (total needed minus current scores total) = 84
So the last round would need a score of 84.
CHECK: Add the four scores 71 + 66 + 67 + 84 = 288
then divide 288 by 4 (number of rounds) = 72 (averge score needed)
