Answer:
b) $103,680.
Step-by-step explanation:
The value each year is 120 % of the previous 10 years.
120 % = 1.2 so we have the equation
V = 50,000(1.2)^n where n is the number of 10 year increments after 1980.
In 2020 4 ten year periods have elapsed so the answer is:
V = 50,000(1.2)^4
= $103,680.
