Marilyn goes to the mall to shop for school clothes. she buys a pair of jeans for $30 and wants to buy a few graphic t-shirts that cost $15 each. if she bought $75 to the mall, what is the maximum number of shirts she can buy? write the answer in an inequality.

oh thats easy

Step-by-step explanation:

it really w

asy

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
