Find the balance in an account that has $700 invested at 5.5% for 4 years compounded semi-annually.

700(1+.055/2)^(2*4) = 869.67

Oh, the joys of compound interest! Let's calculate the balance in your account, shall we?

To start off, I would need to know the compounding period. Did you say it's semi-annually? Alright, I'll keep that in mind.

Now, let's break it down step by step.

First, we need to determine the interest rate per period. Since we are compounding semi-annually, we'll divide 5.5% by 2, giving us 2.75% per half-year.

Next, we calculate the number of periods. In this case, since it's 4 years and we're compounding semi-annually, we have 8 periods (2 periods per year).

Now comes the fun part! We'll use the formula for compound interest:

Balance = Principal * (1 + Rate) ^ Periods

Plug in the values:

Balance = $700 * (1 + 0.0275) ^ 8

Calculating this out, we find that the balance in your account after 4 years would be approximately $832.12! So, there you have it – a little mathematical magic bringing a smile to your face!

To find the balance in an account that has $700 invested at 5.5% for 4 years compounded semi-annually, you can use the formula for compound interest:

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

Where:
A = the final balance
P = the principal amount (initial investment)
r = the annual interest rate (in decimal form)
n = the number of times interest is compounded per year
t = the number of years

In this case:
P = $700
r = 5.5% = 0.055 (converted to decimal form)
n = 2 (compounded semi-annually, meaning twice a year)
t = 4 years

Plugging in these values into the formula, we have:

A = 700(1 + 0.055/2)^(2 * 4)

Simplifying:

A = 700(1.0275)^(8)

Calculating:

A ≈ $822.67

So, the balance in the account after 4 years will be approximately $822.67.

To find the balance in the account, we can use the formula for compound interest:

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

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

In this case:
P = $700 (initial investment)
r = 5.5% = 0.055 (as a decimal)
n = 2 (compounded semi-annually, meaning twice per year)
t = 4 years

Plugging these values into the formula, we get:

A = 700(1 + 0.055/2)^(2*4)

Now, let's solve the equation step by step:

1. Calculate the value inside the parentheses:
(1 + 0.055/2) = 1.0275

2. Raise that value to the power of (2*4):
1.0275^(2*4) = 1.0275^8 = 1.13139375

3. Multiply the result by the principal amount:
700 * 1.13139375 = $791.97

Therefore, the balance in the account after 4 years, compounded semi-annually, would be approximately $791.97.
