Answer:
11.3%
Step-by-step explanation:
In this scenario a painting was bought at present value of $145,000 and sold at future value of $307,000. The time is 7 years in the future.
Return on investment is the gain on original cost of a project. A positive return on investment will result in profit of the project.
To calculate annual rate we use the following formula
Present value = Future value (1 + rate) ^ -number of years
145,000 = 307,000 {(1+r) ^ -7}
145,000/307,000 = (1+r) ^-7
0.4723 = (1 + r) ^ -7
1.113 = 1+ r
r = 0.113= 11.3%
