First find the amount Cassandra must finance.

Sales tax = 0.078(16870) = $1,315.86
Total cost = 16870 + 1315.86 + 895 + 68 = $19,148.86
Amount financed = 19,148.86 − 1,800 = $17,348.86

Monthly rate r = 0.123/12 = 0.01025, number of months n = 48.
Monthly payment A = r·PV / [1 − (1 + r)^−n]
A = 0.01025(17,348.86) / [1 − (1.01025)^−48] ≈ $459.7

The closest answer choice is (b) $459.42.
