A real estate agency has fixed monthly costs associated with rent, staff salaries, utilities, and supplies. It earns its money by taking a percentage commission on total real estate sales. During the month of July, the agency had total sales of $832,000 and showed a net income (after paying fixed costs) of $15,704. In August total sales were $326,000 with a net income of only $523.
(a) Use a formula to express net income as a linear function of total sales. Let N be the net income in dollars, and let s be the total sales in dollars. (Round the terms to two decimal places.)
N(s) =
(I found slope to be 0.03, but when I tried to find the equation of a line I got it wrong.)
(b) What percentage commission does the agency take on the sale of a home? (Round your answer to two decimal places.)
(...How would I even begin to find this?)
