2450 + 150x =350 5. You spend half of your allowance at the movies, and you mow lawns over the weekend to earn an extra $12. If you currently have $25, how much allowance did you receive?

I think 37

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
