The equation V=-3000 +21000 can be used to find the value V of a car at the end of t years.

1.What is the value of the car at the end of 5 year?

2. In how many years is the car worth 12,000?

3. Is it true that the car will be worth $200 after 7 years?

4. How much did the car originally cost?

where is t in the equation ?

anonymous · Answer

3000t type there

typo!

ok wait

anonymous · Answer

you plug in the value of t in the equation... and you will get the value (V) of the car. thus...$$V= -3000*5+21000=(21-3)*1000=18 000$$$

oups... no no
its 21-15= 6 000 $

anonymous · Answer

its a matter of plugging in the number in the equation and you will get the answer for each question. have fun and fan me if you understood

anonymous · Answer

okay so when I do the second problem do I plug in the 12,000 to the t?
