this problem is a present worth problem, where you need to calculate its present amount. this can be solved using the formula:
P = F(1+i)^(-n)
where p is the present value
f is the future value
i is the interest rate
n is the number of years
substituting the given to the formula
P = (500000) ( 1 + 0.1)^(-20)
P = 74,321 is current value of the inheritance that is 500,000 that 20 years from now
