Final answer:
The principal needed to yield $900 in interest at 5% over 8 years is $2250.
Step-by-step explanation:
To calculate the principal required to yield $900 in interest at 5% over 8 years, we can use the formula:
- Interest = Principal × Rate × Time
- $900 = Principal × 0.05 × 8
- Divide both sides of the equation by (0.05 × 8) to isolate Principal
- Principal = $900 / (0.05 × 8)
- Principal = $2250
Therefore, the principal needed to yield $900 in interest at 5% over 8 years is $2250.
