Jack Fuller estimates that the break-even point for EM5, a standard electrical motor, is 500 motors. For any motor that is not sold, there is an opportunity loss of $15. The average sales have been 700 motors, and 20% of the time sales have been between 650 and 750 motors. Jack has just been approached by Radner Research, a firm that specializes in performing marketing studies for industrial products, to perform a standard marketing study. What is the most that Jack would be willing to pay for market research?
