y=6
Step-by-step explanation:
Answer:
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.
Answer:
12
Step-by-step explanation:
we can setup an equation and solve for x: 500-25x = 200, where x stands for the number of weeks she withdraws money.
subtract 500 from both sides to get -25x = -300.
multiply each side by -1 to get 25x = 300
divide each side by 25 to get that x = 12
