Carrie is buying bulk candy for a high school fundraiser. she buys 1000 candy bars for $350. what is the unit cost per candy bar? a) $.30 b) $.35 c) $.45 eliminate d) $1.35

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:

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
