Dorthy purchased a used that depreciate under a straight line method. the initial value of the car 8400 and the salvage value is 400 if the car is expected to have a useful life for another 5 years how much would it depreciate each year? ( answer quickly)a. 2000.00b. 1600.00c. 80.00d. 400.00

B. 1600.00

It would depreciate 1600 per year

Step-by-step 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

the first one

step-by-step explanation:

just id the test.
