Answer:
i = $70000 * 0.05 * 15 = $52500 in simple interest.
Step-by-step explanation:
Use the formula for simple interest:
i = p * r * t, where p is the principal amount, r is the interest rate as a decimal fraction, and t is the number of years.
Here,
i = $70000 * 0.05 * 15 = $52500 in simple interest.
