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?

Solutions

Expert Solution

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.

Time Value of Money: Annuities Many assets provide a series of cash inflows over time; and many obligations require a series of payments. When the payments are equal and are made at fixed intervals, the series is an annuity. There are three types of annuities: (1) Ordinary (deferred) annuity, (2) Annuity due, and (3) Growing annuity. One can find an annuity's future and present values, the interest rate built into annuity contracts, and the length of time it takes to...
