The price of an item is initially $900. For the first 4 years the price increases by $35 each year. For the next 4 years the price decreases by $20 per year. From then on the price increases by $35 per year. Find a piecewise-defined function P that specifies the price of the item after t years have passed. Let P(t) = the price of the item in dollars after t years have passed. (Note: Do not use $ signs within your answers.)

(b) When 4 < t  8 the value of P(t) is given by what part of the piecewise-defined function?

anonymous · Answer

should be 4 < t < or = 8
