Problema Solution
A golfer recorded 5 scores for five rounds of golf one week. Four of these rounds were the same, and one was 10 strokes higher than the others. If the average score for the week was 83, what was the score for each of the five rounds?

let for four rounds golfer made x and for firfth it is x+10
average = {x+x+x+x+(x+10)}/5 = 83
5x+10 = 415
x = 405/5
so x = 81 (score for four rounds)
x+10 = 91 for fifth
