1. Assume that the marginal cost (MC) of bok choy production is $15/box (bok choy production is measured in boxes). Also assume that the price of bok choy is $12/box. Interpret the value of the marginal cost (MC) and interpret the value of the marginal revenue (MR). Make sure to use the relevant units provided. Do not make your answer generic. Also, calculate the change in total profit if you increase production of bok choy by one box. Show your work and be clear on the sign of the result. MC: $15 / box price of bok choy: $12 / box
