The Canadian Parka Company manufacturers two kinds of coats. The Canuck and Snowbird coats can be sold at wholesale for $50 and $25 respectively. The Canuck coat requires 2 square meters of blue fabric, and 1 square meter of green fabric. The Snowbird coat requires 1 square meter of blue fabric and 2 square meters of green fabric. The shop only keeps 20 square meters of blue fabric and 20 square meters of green fabric on hand but can purchase additional green fabric for $2 per square meter, or additional blue fabric for $5 per square meter. How many of each coat should be produced to maximize net profit?
