Answer:
A. V = 116050 - 5300t
B. $73,650.
Step-by-step explanation:
10050 = 116050 - 20k where k is the depreciation every year.
20k = 116050 - 10050 = 106000.
k = 106000 / 20
k = 5300
So the answer to A is:
V = 116050 - 5300t where t = number of years old the bulldozer is.
B. Value after 8 years
= 116050 - 5300*8
= 73,650 dollars.
