Each of the 59 members in a high school class is required to sign up for a minimum of one and a maximum of three academic clubs. the three clubs to choose from are the poetry club, the history club, and the writing club. a total of 22 students sign up for the poetry club, 27 students for the history club, and 28 students for the writing club. if 6 students sign up for exactly two clubs, how many students sign up for all three clubs?

The  the number of students who sign up for all three clubs = 6

The total number of students in the class is given by:

Total number of students= Number of students in poetry club+Number of students in history club+Number of students in writing club-Number of students in exactly 2 clubs-2×Number of students in all the three clubs.

Based on the information we have:

Total number of students= 59

Number of students in poetry club= 22

Number of students in history club= 27

Number of students in writing club= 28

and number of students in exactly two clubs=6

Let the number of students in the three club= x

Hence, we have:

59=22+27+28-6-2x

i.e.

59=71-2x

i.e.

2x=71-59

i.e.

2x=12

i.e.

x=6

Hence, the answer is: 6

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
