Plastic Pipe Company manufactures a variety of pipes, and has received a special one- time-only order from a new customer. Plastic Pipe has sufficient idle capacity to accept the special order to manufacture 2,000 16-foot lengths of pipe at a price of \($8.00\) per pipe. Plastic Pipe's normal selling price is \($12.00\) per 16-foot length. Variable manufacturing costs are \($7.00\) per pipe and fixed manufacturing costs are \($1.00\) per pipe. Plastic Pipe's variable selling expense for its normal line of pipes is \($0.50\) per pipe. What would the effect on Plastic Pipe's operating income be if the company accepted the special order?
