Question 1176972
exponential
P=Ae^kt
12000=220000e^5k
12/220=e^5k
ln both sides
-2.909=5k
k=-0.5817
-
after 3 years
P=220000*e^(-1.745)
P=k38,412.96 rounding at end 
-
straight line
(0, 220)
(5, 12)
slope is 208/-5=-41.6 thousands
It decreases k41,600 a year for 3 years or 124,800 less.
220,000-124,800=K95,200
The book value would be k56,787 more
