$765.13 is deposited at the end of each month for 3 years in an account paying 2% Interest compounded monthly. Find the final am
Crank

Answer:

Option B.

Step-by-step explanation:

The future value formula, for an annuity, is:

FV = \frac{P((1+r)^{n} - 1)}{r}

An annuity means that a number of payments happen during the period(an year, for example).

P is the value of the deposit, r is the interest rate, as a decimal, and n is the number of deposits.

In this question:

Deposits of $765.13, so P = 765.13

Each month, for 3 years. An year has twelve months, so n = 3*12 = 36

2% Interest a year. An year has 12 months, so r = \frac{0.02}{12} = 0.00167

Find the final amount of the account.

FV = \frac{765.13*((1 + 0.00167)^{36} - 1)}{0.00167} = 28,363.46

The final amount of the account will be $28,363.46, which is option B.

The following blank indicates a missing operation in the equation.
Natalija [7]
The answer would be 5/2q+9r+6r-20s

Explanation
We have the equation
5(1/2q+3r-4s)
which would equal
5/2q+15r-20s

so with the information
We can subtract 6r from 15r to get 9r
15r-6r=9r
+9r would be the missing piece

So we substitute it in to make the equation true.
5/2q(+9r)+6r-20s
Hope this helps or was correct
