The table below shows the price of inputs and the price of outputs at each step in the production process of making a shirt. Assume that each of these steps takes place within the country. Instructions: Round your answers to two decimal places. a. Using the standard expenditure method, the total contribution of this shirt to GDP is: $ b. If we use a value-added method (i.e., summing the value added by producers at each step of the production process, equal to the value of output minus the price of inputs), the contribution of this shirt to GDP is: $ c. If we mistakenly added the price of both intermediate inputs and final outputs without adjusting for value added, we would find that this shirt contributes: $ to GDP
