Hillary is looking for a gym to join. Oym A offers a membership for $25 a month with no sign-up fee . Gym B offers a membership for $20 a month with a $10 sign-up fee.

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

step-by-step explanation:

u take $75 minus $60.the anwer/original($75)multiply by 100

the answer is 62.8 cubic units
