In a field day at a school, each child who competed in \(n\) events and scored a total of \(p\) points was given an overall score of \(\frac{p}{n} + n\). Andrew competed in 1 event and scored 9 points. Jason competed in 3 events and scored 5, 6, and 7 points, respectively. What was the ratio of Andrew's overall score to Jason's overall score? A. \(\frac{10}{23}\) B. \(\frac{7}{10}\) C. \(\frac{4}{5}\) D. \(\frac{10}{9}\) E. \(\frac{12}{7}\)

A. \(\frac{10}{23}\)
B.\(\frac{7}{10}\)
C. \(\frac{4}{5}\)
D.\(\frac{10}{9}\)
E. \(\frac{12}{7}\) It should be DFor readers, denominator for P is just 1 n. The fraction then adds into so you can rewrite it as \(n + \frac{p}{n}\) for a clearer understanding. Andrew: \(1 + \frac{9}{1}\) \(= 1 + 9 = 10\) Jason: \(3 + \frac{(5+6+7)}{3}\) \(= 3 + \frac{18}{3} = 9\) Andrew : Jason \(= 10 : 9\)

Answer D
Andrew: n=1, p=9 So: 9/1+1=10 Jason: n=3, p=5+6+7=18 So: 18/3+3=9 Ratio: 10/9

Andrew's overall score = \(\frac{9}{1} + 1 = 10\). Jason's overall score \(= \frac{5+6+7}{3} + 3 = 6+3 = 9\). Ratio = \(10:9\). Ans  D.

A. \(\frac{10}{23}\)
B. \(\frac{7}{10}\)
C. \(\frac{4}{5}\)
D. \(\frac{10}{9}\)
E. \(\frac{12}{7}\) Since Andrew competed in 1 event and received 9 points, his overall score was: 9/1 + 1 = 10 Since Jason completed in 3 events and scored 5, 6, and 7 points, he scored a total of 18 points and his overall score was: 18/3 + 3 = 9 Thus, the ratio of Andrew’s score to Jason’s score is 10/9. Answer: D

Andrew / Jason = X = Ratio of andrews overall over Jason's overall
Andrew = P/n + n = 9/1 + 1 = 1 9/1 = 10/1 = 10 = Andrews overall score Jason = 18/3 + 3 = 3 18/3 = 27/3 = 9 = Jason's overall score X = 10/9
Therefore, the correct answer is (D) 10/9
Good warm up question. I wonder what level it is.

Is there really a need of word " respectively" in the question? What difference will it make with or without this word?
The reason i ask is this word made me calculate the three rates Separately at first and then redo my calculations again.

Word "respectively" adds emphasize that you need to calculate each set of point i.e, 5, 6 , and 7 for 1 game only. Means 5/1, 6/1, and 7/. And not 5/1 + 1, 6/1 + 1 etc. Though I did it wrong. QZ
