answer as soon as possible please

Suppose there are two individuals and two time periods. The demand [marginal willingness to pay] for a public resource is given by: Demand at time 0 Demand at time 1 Individual A WTPAJO = s 2o WTPAJI = 9 2o Individual B WTPB'C. = 10 4o WTPBJ = 13 40 The marginal cost of supplying the resource is a constant S4 in both periods. (a) What is the efficient amount of the resource to supplyr in each period? That is, solve for G0 and Gil. {b} What are the net benets of the resource in each period? That is, solve for N80 and N81. (c) Use the values from part (b) to calculate the present value of the net benefits of this resource. Assume the discount rate is 10%
