An engineer has invented a new high-speed wireless charging system. The engineer is considering selling the patent to a cellular phone manufacturer. The manufacturer offers 15 annual payments, starting with $60,000 at the end of the first year, $65,000 at the end of the second, and so forth, increasing by $5,000 each year (i.e., the last (15-th) payment will be $60,000 + (14x$5,000). Assume the engineer uses a MARR of 10%, calculate the Future Worth of this offer (at the end of the 15-th year). $2,427,206. $2,744,926. $2,388,629. $2,931,669. $2,117,109
