Find the percentage of change. In 2016, 136.75 million votes were cast for the presidential election. In 2020 151.8 million votes have been counted . What’s the percentage of change ?

  11.0% increase

Step-by-step explanation:

The percentage change can be found from ...

  ((new value)/(old value) -1) × 100%

  = (151.8/136.75 -1) × 100%

  ≈ (1.1100548 -1) × 100%

  ≈ 11.0% . . . . . increase

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
