Step 1 :The value of the painting is given by the function \(V(t)=30000 \times e^{0.147 t}\), where \(t\) is the number of years since 1950.
Step 2 :To find the value of the painting in 2024, we need to substitute \(t=2024-1950=74\) into the function.
Step 3 :The value of the painting in 2024 is approximately \$1,589,924,965.64.
Step 4 :To find the rate of change of the painting's value in 2024, we need to find the derivative of the function \(V(t)\) and then substitute \(t=74\) into the derivative.
Step 5 :The derivative of \(V(t)\) is \(V'(t)=30000 \times 0.147 \times e^{0.147 t}\).
Step 6 :The rate of change of the painting's value in 2024 is approximately \$233,718,969.95 per year.
Step 7 :Final Answer: The value of the painting in 2024 is approximately \(\boxed{\$1,589,924,965.64}\) and the rate of change of the painting's value in 2024 is approximately \(\boxed{\$233,718,969.95}\) per year.
