A new car worth $25,000 is depreciating (loses value) in value by $1,250 per year. Determine how many years will it take for the car to be worth $8,500?
Accepted Solution
A:
so, when the car is new is 25000.
after 1 year is 25000 - 1250
after 2 years is 25000 - 1250 - 1250, or just 25000 - 1250(2)
after 3 years is 25000 - 1250 - 1250 - 1250, or just 25000 - 1250(3)
after 4 years is 25000 - 1250(4)
after "x" years is 25000 - 1250x.
so, say the current price is hmmm "y", and "x" is years passed, thus
y = 25000 - 1250x.
we know that after "x" years, the car became worth only 8500, namely y = 8500, thus
