Business miles re-added from the logFails

Page 3 is a second scan of page 2 (D23 says so); the engine summed all four page totals. Business miles 8,100 (not 11,800) of 17,740 driven; car expense 8,100 x 0.7 = 5,670.

Method: Added every trip in the mileage log and fingerprinted each page's trips to catch rescans. p1: 20 trips = 2,600 (page total 2,600); p2: 22 trips = 3,700 (page total 3,700); p3: 22 trips = 3,700 (page total 3,700); p4: 18 trips = 1,800 (page total 1,800)

Proposed: 8,260 → 5,670 · Tax: fed +919 · CA +80
