Final answer:
To calculate the simple interest, multiply the principal, interest rate, and time. The maturity value can be found by adding the principal and interest.
Step-by-step explanation:
To calculate the simple interest, we can use the formula: Interest = Principal × Rate × Time.
Plugging in the given values:
- Principal: $6,400
- Interest Rate: 5% (or 0.05 as a decimal)
- Time: 14 months (or 14/12 years)
Calculating the simple interest:
Interest = $6,400 × 0.05 × (14/12) = $448.
To find the maturity value, we can use the formula: Maturity Value = Principal + Interest.
Calculating the maturity value:
Maturity Value = $6,400 + $448 = $6,848.
