Answer:
The equation to represent the account balance in t years

Explanation:
Given the compound interest equation

here
A represents Accrued Amount (principal + interest)
P represents Principal Amount
I represent Interest Amount
r represents the Annual interest rate
t represents Time Involved in years
n represents the number of compounding periods per unit t
As we are given that the interest is compounded semi-annually
i.e. n = 2
so substituting n = 2 in the equation

∵ n = 2
Thus, the equation to represent the account balance in t years
