Suppose that you borrow $4000.00 from a friend and promise to pay back $7360.00 in 4 years. What simple interest rate will you pay?

the formula on how u calculate the simple interest is P×PRT ( PRICE *RATE *TIME )

THE THING IS WHTS THE RATE IN HERE

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:
