Question

The value V (in dollars) of a vehicle depends on the miles x that it has been driven. This is given in the formula V = 22,000 – 0.25x . After one year, the value of a vehicle is between $12,000 and $15,000.
Which range of miles driven corresponds to this range of values based on the given formula?

Answer 1

Answer:

(28000,40000)      or     $28,000 to $40,000

Step-by-step explanation:

plug in values as V and solve for x:

12,000=22,000-0.25x

-10,000=-0.25x

40,000=x

15,000=22,000-0.25x

-7,000=-0.25x

28,000=x

an interval notation always has the lower value first so its:

(28000,40000) or $28,000 to $40,000
