There are 36 boys on a school bus. If 60% of the students on the bus are girls, how many total students are there? Use a proportion to solve.

54

Step-by-step explanation:

First, we can discover that 40% of the class are boys

100-60=40

Second, we need to work out what ten per cent of the class is, which we get by dividing 36 by 4:

36÷4=9

9 is equal to ten per cent.

Then, we multiply this by 6 because 10×6=60, which is the percentage of girls in the class.

9×6=54

Therefore, we have 54 girls on the bus

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

correct me if i'm wrong and if it is i'm truly sorry.
