A car was purchased for $42,000. Assuming the car depreciates at a rate of $5040 per year (straight-line depreciation) for the first 5 years, write the value v of the car as a function of the time t (measured in years) for $0 \leq t \leq 5$
A) $v ( t ) = 5040 t - 42,000$
B) $v ( t ) = 42,000 - 5040 ( 5 ) t$
C) $v ( t ) = 42,000 - 5040 t$
D) $v ( t ) = 42,000 + 5040 ( 5 ) t$
E) $v ( t ) = 42,000 + 5040 t$

The value of the car decreases by $5040 each year, so the value of the car after t years is the initial value minus the depreciation over t years, which is $42,000 - 5040t$.
