Question

the conditional relative frequency table was generated using data that compares the number of boys and girls who pack their lunch or buy lunch from the cafeteria. 35 total girls and 50 total boys were surveyed. how many students bought their lunch from the cafeteria? round to the nearest whole number.

	cafeteria	pack	total
girls	0.4	0.6	1.0
total	0.42	0.58	1.0

\boxed{} students

Explanation:

Step1: Calculate boys who bought from cafeteria

Multiply boys' total (50) by cafeteria frequency (0.44).
$50 \times 0.44 = 22$

Step2: Calculate girls who bought from cafeteria

Multiply girls' total (35) by cafeteria frequency (0.4).
$35 \times 0.4 = 14$

Step3: Sum the two results

Add boys' and girls' cafeteria buyers.
$22 + 14 = 36$

Answer:

36
