After a 15% increase, the price of a jacket is $69. What was the original price of the jacket before the increase?

✓ Correct Answer: Option B

Let 'P' be the original price. After a 15% increase, the new price is P * (1 + 0.15) = 1.15P. So, 1.15P = $69. Divide $69 by 1.15 to find P: P = $69 / 1.15 = $60.
