To calculate the future value of the deposit with daily compounding, we can use the formula for compound interest:

A = P × (1+ r / n) n×t


Where:

A is the future value of the investment/amount in the account after time t

P is the principal amount (initial deposit) = $30,000

r is the annual interest rate = 5.25% or 0.0525

n is the number of times the interest is compounded per year (daily compounding here based on a 360-day year)

t is the time the money is invested for (8 months or 8/12 years)


Given that the interest is compounded daily based on a 360-day year, the number of compounding periods (n) per year would be 360.


Let's calculate the future value after 8 months:

t = 8/12

t = 2/3

A = 30,000 x (1+ 0.0525 / 360 ) 360 x 2/3

Now, solving this equation gives:

A = 30,000 × (1+0.00014583333) 240

A = 30,000×1.035178603

A = 31,055.3581

Rounded to two decimal places, the amount in the account after 8 months would be approximately $31,055.36. None of the provided options match this exactly, but the closest one is c. $31,056.91.
