Molly have 97,905 and the same with account the interest rate is 2% per year and is not compounded how much interest will she earn in 8 months use the formula I equals PRT where is the interest p is the principal or is the interest rate expressed as a decimal and t is the time in years

1 answer

To calculate the interest earned using the formula \( I = PRT \), where:

  • \( I \) is the interest,
  • \( P \) is the principal amount,
  • \( R \) is the interest rate (expressed as a decimal),
  • \( T \) is the time in years.

Let's break this down step by step:

  1. Identify the values:

    • \( P = 97,905 \) (the principal amount)
    • \( R = 2% = 0.02 \) (the interest rate expressed as a decimal)
    • \( T = \frac{8 \text{ months}}{12 \text{ months/year}} = \frac{2}{3} \text{ years} \)
  2. Substitute the values into the formula: \[ I = 97,905 \times 0.02 \times \frac{2}{3} \]

  3. Calculate:

    • First, calculate \( 97,905 \times 0.02 \): \[ 97,905 \times 0.02 = 1,958.10 \]

    • Then multiply by \( \frac{2}{3} \): \[ I = 1,958.10 \times \frac{2}{3} = 1,305.40 \]

So, the total interest Molly will earn in 8 months is $1,305.40.
