This problem stumped me. how do i find the percent change?

The percent change is 56.7%

Decrease

Step-by-step explanation:

x% of 120 meals is 52 meals

x% * 120 = 52

x/100 * 120 = 52

x = 52 * 100 / 120

x = 43.3%

100% - 43.3% = 56.7%

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
