The employees at a bank ordered 5 turkey sandwiches and 3 salads from a local deli. The total cost for the order was $49. If a salad costs $1 less than a turkey sandwich, what is the cost of a turkey sandwich and the cost of a salad

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

47 - 90 = 43

43 - 180 = x

x = 137
