Answer 2

Calculation of Interest:

To calculate the amount of money that will be on the account after one year with an interest rate of 15% per annum, we can use the formula for compound interest:

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 (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 700 rubles, the annual interest rate (r) is 15% (or 0.15 as a decimal), the number of times interest is compounded per year (n) is not specified, and the number of years (t) is 1.

Since the compounding frequency is not specified, we will assume that the interest is compounded annually.

Plugging in the values into the formula, we get:

A = 700(1 + 0.15/1)^(1*1)

Simplifying the equation:

A = 700(1 + 0.15)^1

A = 700(1.15)

A = 805 rubles

Therefore, after one year, the account will have 805 rubles if no other transactions are made, and only the interest is added to the account.
