    Given that the value of a copy machine decreases according to the function: v (t) = 11200 (4) ^ (-0.12t), where, t is the number of years that have elapsed since the machine was purchased and v (t) is the cost of the machine in dollars. The time it takes for the machine to cost $2 800 can be determined by simply using the function and setting v (t) to be equal to $2 800. After calculating, the result is that the machine will cost $2 800 after 8.33 years of purchasing it.
