Answer 2

Calculation of Interest on Deposit

To calculate the amount that will be on the account after one year with an annual interest rate of 4%, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where: - A is the final amount on the account - P is the initial amount (principal) - r is the annual interest rate (expressed as a decimal) - n is the number of times the interest is compounded per year - t is the number of years

In this case, the initial amount (P) is 40,000 rubles, the annual interest rate (r) is 4% (0.04 as a decimal), and we want to calculate the amount after one year (t = 1).

Let's plug in the values into the formula:

A = 40,000(1 + 0.04/1)^(1*1)

Simplifying the equation:

A = 40,000(1 + 0.04)^1

Calculating the expression inside the parentheses:

A = 40,000(1.04)^1

Evaluating the exponent:

A = 40,000(1.04)

Calculating the final amount:

A = 41,600 rubles

Therefore, after one year, the amount on the account will be 41,600 rubles.
