TABLE 2- 3
Every spring semester, the School of Business coordinates a luncheon with local business leaders for graduating seniors, their families, and their friends. Corporate sponsorship pays for the lunches of each of the seniors, but students have to purchase tickets to cover the cost of lunches served to guests they bring with them. The following histogram represents the attendance at the senior luncheon, where X is the number of guests each student invited to the luncheon and f is the number of students in each category.

-Referring to the histogram from Table 2-3, if all the tickets purchased were used, how many guests attended the luncheon?
A) 275
B) 388
C) 4
D) 152

Quizplus · Accepted Answer

To find out how many guests attended the luncheon, we need to multiply each value on the x-axis by its corresponding frequency (i.e., number of students). We can see that the total number of guests would be (0 x 15) + (1 x 26) + (2 x 39) + (3 x 24) + (4 x 6) = 275. Therefore, the answer is B.
