1. An engineering company in Wyoming that owns 50 hectares of valuable land has decided to lease the mineral rights to a mining company. The primary objective is to obtain long-term income to finance ongoing projects in years 6 and 16 from the present time. The engineering company makes a proposal to the mining company that it pay $20K per year for 20 years beginning 1 year from now, plus $10K six years from now and $15K sixteen years from now. If the mining company wants to pay off its lease immediately, how much should it pay now if the investment should make 16% per year?
