This problem is a reiteration problem. That is not the right way to solve the problem. The problem did not say total score as in the total score at the end of the game. It states the total score at the end of each QUARTER. Which means it’s 15 for Q1 and 15+2/7*15 for Q2 and 1/4(15+2/7*15) +15+2/7*15 for Q3 and Q4 is just 11. This is the way to solve the problem if the numbers were integers at the end of each quarter. But technically you cannot score 30/7 points in any quarter. This problem has a lot of flaws.
