Question

Roger completes a quiz with these rules: 5 points are given for each right answer, 2 points are lost for each wrong ans. Roger gets 6 questions correct and 4 questions wrong. What is roger's final score ?

Answer 1

The final score of Roger is 22.

Explanation:

The final score (F) of Roger is given by:

`F = 5R - 2W`

Where R is the right answers and W is the wrong answers

Since he gets 6 questions correct (R = 6) and 4 question wrong (W = 4) we have:

`F = 5R - 2W = 5*6 - 2*4 = 22`

Therefore, the final score of Roger is 22.
