A bakery sold a total of 500 cupcakes in a day, and 200 of them were mocha flavored. What percentage of cupcakes sold that day were mocha flavored?

20%

Step-by-step explanation:

200 mocha flavored cupcakes of the 500 cupcakes were sold. (200/500).

Reduce to 2/5. Then multiply 20/20 to 2/5 and get 20/100.

20% cupcakes were mocha flavored.

The logic behind me rewriting the fraction to 20/100 was because 200/500 could easily be divided be 100 and 5.

40%

Step-by-step explanation: 200/500=?/100

2/5 x 20/20= 40/100

40%

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
