Mr. Crawford is ordering pizzas and breadsticks for a school pizza party and has a budget of $81, but no more. An order of breadsticks costs $7 and a pepperoni pizza costs $13. Write an inequality that represents the above situation if x represents the number of bread sticks and y represents the number of pizzas.
Group of answer choices

x+y<81

x+y<20

7x+13y≥81

7x+13y≤81

Step-by-step explanation:

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
