Braden has $700 in an account that earns 10% interest compounded annually.

To the nearest cent, how much will he have in 3 years?

1 answer

To calculate the amount Braden will have in 3 years with an initial investment of $700 at an annual interest rate of 10% compounded annually, we can use the formula for compound interest:

\[ A = P(1 + r)^n \]

Where:

  • \(A\) is the amount of money accumulated after n years, including interest.
  • \(P\) is the principal amount (the initial amount of money).
  • \(r\) is the annual interest rate (decimal).
  • \(n\) is the number of years the money is invested or borrowed.

For Braden's case:

  • \(P = 700\)
  • \(r = 0.10\) (10% expressed as a decimal)
  • \(n = 3\)

Now we can plug in the values:

\[ A = 700(1 + 0.10)^3 \] \[ A = 700(1.10)^3 \]

Calculating \(1.10^3\):

\[ 1.10^3 = 1.331 \]

Now substitute back into the formula:

\[ A = 700 \times 1.331 \] \[ A = 931.70 \]

Thus, to the nearest cent, Braden will have $931.70 in 3 years.
