Maria finds a local gym that advertises 31 training sessions for $883. Find the cost of 89 training sessions.

 $2,534.72

Step-by-step explanation:

$883.00 / 31= $28.4838 round to $28.48

$28.48 x 89=$2,534.72

answer: the answer is 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
