Can you guys pls me out with 16 and 17

16. $ 4100

17. y = 10000 - 750x

Step-by-step explanation:

16)

As initial value is $ 5000, and salvage value is $ 500. That means in 5 years value decreased by 5000-500 = 4500 so ,

in 5 year value decreased =  4500

in 1 year value decreased =  4500/5 = 900

so per year 900 $ gets decreased from original price. So equation can be given as

V = 5000 - 900y

where V is value of a vehicle and y is number of year

So after 1 year value would be

V = 5000 - 900 x 1 = 5000 -900 = 4100 $

17)

initial cost of car = $ 10000

per year amount decreases by  =  $ 750

then equation can be given as

y = 10000 - 750x

where x is number of year and y is cost of car after x year.
