An electronic shop has an annual Macbook. Sale of a certain model. Last year, they sold
100 MacBooks, and each computer is about 1,000$. It was determined that for a 100$
decrease in price, 20 Macbooks would sold, and for every hundred dollar increase, 20 fewer
MacBooks were not sold. The cost of each Macbook repair is 200$. The integer value of
money increases or decreases will be used. Predict the equation R of x to depict the
revenue from the Mac book sale. Let x represent the number of 100$ increases or
decreases. Predict the domain of this function.
