The clearance sale advertised 1/3 off the list price of clothes and 1/2 off the list price of luggage. ramon bought a suitcase with a list price of $100 and a coat with a list price of $195. what was his total bill?

a. $115
b. $150
c. $180
d. $295

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

graph of this function as shown below:

it would be:
