In fact, they feel that demand is given by. p = (6,000 7) .2y, for 7 2 0, where 7 is a parameter reecting demand uncertainty. According to market research, given the proposed plant size, 10,000 units, each PC can be sold for p = $4000 7. If demand is as expected, then 7 = 0, and p = $4000. However, if demand shifts downward by \"y, then p = $4000 '7. For what range of demand shifts does the proposed project have a nonnegative NPV? (a) $343.36 2 7. (b) $2656.64 2 7. (c) $1,656.64 2 7. (d)* $656.64 2 *y
