X2-X1 A collaborative federal and state program has been proposed in response to acid rain damage in Newport Bay, Maryland. To estimate the incremental benefits of the program, you use the travel cost method based upon the following pre- and post-policy recreational demand functions: Pre-policy: P = 62 -0.02V, Post-policy: P= 80 -0.02Vz, where Vis the number of visitors (in thousands) and P is the admission fee. Assume the admission fee is set at $20 per visitor. 9. The number of pre- and post-policy visitors, V, and V2, (in thousands) is and respectively.
