Yesterday, Robert's Doughnut Shop sold 1/3 as many chocolate doughnuts as cinnamon doughnuts. If they sold 5 trays of cinnamon doughnuts, how many trays
of chocolate doughnuts did they sell?
Write your answer as a fraction or as a whole or mixed number.
trays

5/3 trays

Step-by-step explanation:

if they sold 1/3 as many chocolate as cinnamon you just multiple 5 by 1/3 which equals 5/3

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
