Astudent taking a test consisting of 10 questions is told that
each questions after the first is worth 2 marks more than the
preceding question. if the third question of the test is worth 5 marks.
what is the maximum score that the student can obtain by attempting
8 questions?

96 points

Step-by-step explanation:

Because each question is worth more than the previous one, a student would obtain the highest score answering only 8 questions by skipping the first two and answering questions 3-10. Question 3 is worth 5 points and each question is worth 2 more points than the previous one, so if you got questions 3-10 right you'd get 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 = 96 points.

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
