Ok, they give us the forumla so all we have to do is input are data and work it out.
f(x) = 2x + 54

They tell you that f(x) is the income and x is the area. They also tell you what he has earned {204, 344, 450, 482} so all we have to do is input what he has earned where f(x) is located and solve for x. Are you still there and do you understand or need more help? I will setup the first one.

204 = 2x + 54
Now solve for x. Once you find x, it will be a number in one of your answer.
