Answer:
B. 1600.00
It would depreciate 1600 per year
Explanation:
Since,
Dorthy purchased a used that depreciate under a straight line method
so, we can use linear equation formula
We are given
initial value of car is 8400
so,
we can use slope-intercept form of line
now, we can plug value
the salvage value is 400 if the car is expected to have a useful life for another 5 years
so, at x=5 , y=400
we can plug it and solve for m
So,
It would depreciate 1600 per year
