A DVD that originally cost $30 is on sale for 10 percent off. Complete the steps to solve the problem Step 1: Find the amount of the discount.
($30.00)(0.10) =
Step 2: Subtract the discount from the original amount to find the sale price,

3$

Step-by-step explanation:

the discount is 27 so that leaves 3 dollars if

30-27=3 ^^

answer: slight chance that it will happen

step-by-step explanation:

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
