Answer 2

Calculation of Compound Interest

To calculate the value of the deposit after 3 years with compound interest, we can use the formula:

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

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

In this case, the principal amount (P) is 1000 rubles, the annual interest rate (r) is 20% (0.20 as a decimal), and the deposit is compounded annually (n = 1). The time period (t) is 3 years.

Plugging in the values into the formula, we get:

A = 1000(1 + 0.20/1)^(1*3)

Simplifying the equation:

A = 1000(1 + 0.20)^3

Calculating the values:

A = 1000(1.20)^3

A = 1000(1.728)

A ≈ 1728 rubles

Therefore, the value of the deposit after 3 years with compound interest will be approximately 1728 rubles.
