e. colby richards is paid a salary of $125 a week and a 3% commission on all
sales he makes above $2,000 for the week. what total earnings did he have for
a week in which his sales were $2.890?

Step-by-step explanation:

sorry I don't know this question I'm very very sorry. why am I even here if I don't know the awnser to this? hopefully somewhere near the future I learn these type of problems. so I can get better at awnsering these.

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
