Step-by-Step Solution

Compound Interest Formula: FV = P × (1 + r/m)^(m×t)
  Principal (P):         $850,000.00
  Annual Rate:           7.35%
  Compounding:           quarterly (m = 4)
  Total periods (n):     34
  Rate per period (r/m): 1.8375%

  FV = $850,000.00 × (1 + 1.8375%)^34
  FV = $850,000.00 × 1.857218
  FV = $1,578,634.98

  Interest Earned = FV − Principal = $1,578,634.98 − $850,000.00 = $728,634.98
