Answer

Answer:

36

Explanation:

Step1: Calcular número de chicos que compran

Multiplicamos el total de chicos (50) por la frecuencia relativa de chicos que compran en la cafetería (0.44). $50\times0.44 = 22$.

Step2: Calcular número de chicas que compran

Multiplicamos el total de chicas (35) por la frecuencia relativa de chicas que compran en la cafetería (0.4). $35\times0.4=14$.

Step3: Calcular total de estudiantes que compran

Sumamos el número de chicos y chicas que compran. $22 + 14=36$.
