Step-by-step explanation:

S. I = PRT/100

now since you're aiming at $20,000 and what you deposited was $12,500, this means that you're looking to raise 20,000-12,500 = $7,500 simple interest.

Hence, S. I = 7,500

P = 12,500

R = 6.5%

T = ?

Substituting these values into the simple interest equation:

7,500 = (12,500 * 6.5 * T) / 100

T = (100 * 7,500) / (12,500 * 6.5)

T = 750000/81,250 = 9.23 approximately 9 years
