Question 944061
NPV= [-$310000 x P] + [ $207000 x 0.48] + [ $398000 x (1 - 0.48 - P)]
Do the math and write it as: 
NPV = [-310000P] + 99360 + [398000(.52 - P)]
More math
NVP = -310000P + 99360 + 206960 - 398000P 
Gather like terms
NVP = -310000P - 398000P + 306320
NVP = -708000P + 306320
708000P + NVP = 306320
P(708000 + NV) = 306320
P = {{{(306320)/(NV+708000)}}}
