Answer

Answer:

36

Explanation:

Step1: Calculate number of boys who bought lunch

Multiply total boys by cafeteria - relative - freq. $50\times0.44 = 22$

Step2: Calculate number of girls who bought lunch

Multiply total girls by cafeteria - relative - freq. $35\times0.4=14$

Step3: Calculate total students who bought lunch

Sum up boys and girls who bought lunch. $22 + 14=36$
