Project A: N = 5; PMT = 5,000; FV = 0; I/Y = 12; CPT → PV = 18,024; NPV for Project A = 18,024 − 15,000 = 3,024.
Project B: N = 5; PMT = 7,500; FV = 0; I/Y = 12; CPT → PV = 27,036; NPV for Project B = 27,036 − 25,000 = 2,036.
For independent projects the NPV decision rule is to accept all projects with a positive NPV. Therefore, accept both projects.
