Your adjusted (net) capitalized cost is 59665 + 995 - 7500 = 53160. Your monthly payment before tax is calculated as follows…
0.00273 x (53160+32845.80) + (53160 - 32845.80) / 36 = 799.08
It appears that your sales tax rate is 6.25% and so, your monthly payment, including tax, amounts to…
799.089 x 1.0625 = 849.02
Hope this helps…
