The value of a famous work of art increases over time according to dA kA , where t is time in years dt
since 1990, when the artwork was worth $6000. In the year 2000,
it sold at auction for $14000.
a) Build a general form of the function A(t), and use that and the
above information to determine the
growth constant, k. Round it to 4-decimal places.
b).Write out the fully determined function.
c).Use your function to determine the estimated value of the artwork this year, 2020, rounded to the nearest $1
d).How many years from 1990 until the artwork is worth $200,000?
We are given that dA/dt= Kdt then, by variable separable method, we will solve the given differential equation and with the help of the initial condition A(0)= 6000 and the given condition that A(10)= 14000, we will get the value of K.
Then, the fully determined function A(t) will be found out, as explained in the solution provided below.
