6. On page 91 the effect of changing the price of the product was described. With Table 4-2 as a starting point, recompute TVP and MVP using the two additional product prices discussed ( $2 /unit, and $.50 /unit). Construct a graph and plot these MVP curves, as well as the MVP curve when Py=$1.00 /unit. What is the optimal rate to use X1, at each of these prices, given Px1=$5.00 /unit? Do these adjustments in response to product price changes make sense? 6. On page 91 the effect of changing the price of the product was described.
