Avery's class sold candy bars for a fundraiser. there were 20 bars in each box. avery sold 4 boxes and an additional 8 bars. express the total number of boxes that avery sold as a mixed number. how many candy bars did avery sell? a) 4 2 5 boxes; 88 candy bars b) 4 1 5 boxes; 88 candy bars c) 4 3 5 boxes; 80 candy bars d) 4 2 5 boxes; 72 candy bars 6)

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
