A delivery company purchased a new delivery truck for $43,200. The depreciated value of the truck can be estimated by the number of t years in service. Suppose the truck depreciates at a rate of $7,200 per year, formulate a function ƒ(t) that can be used to estimate the truck's depreciated value after t years.
Responses
A ƒ(t) = 7,200t − 43,200t
B ƒ(t) = 43,200 + 7,200t
C ƒ(t) = 43,200 − 7,200t
D ƒ(t) = 43,200t − 7,200t
