In professor shannon's economics class there are 12 male students. females represent 60% of the class total. how many students does professor shannon have in his economics class?

Respuesta :

he has 30 students in his class because 40% of the class is boys and there is 2.5 40% in 100% so we do 12 x 2.5

Answer:

There are total 30 students in the class.

Step-by-step explanation:

Let the total number of students in class = x

Number of males in the class = 12

Number of females in the class = 60% of Total students = 60% of x = 0.6x

So, we get that,

Number of males + Number of females = Total students

i.e. [tex]12+0.6x=x[/tex]

i.e. [tex]12=x-0.6x[/tex]

i.e. [tex]12=0.4x[/tex]

i.e. [tex]x=\frac{12}{0.4}[/tex]

i.e. x = 30

Thus, there are total 30 students in the class.
