Answer:
Total = Principal × (1 + Rate) ^ years
then solving for rate:
log(1 + rate) = {log(total) -log(Principal)} ÷ Years
log(1 + rate) = {log (10,560) -log(8,800)} ÷ 4
log(1 + rate) = {4.0236639182 -3.9444826722} ÷ 4
log(1 + rate) = 0.079181246 / 4
log(1 + rate) = 0.0197953115
10 ^ 0.0197953115 = 1.0466351394 = 1 + rate
rate = .0466351394 or 4.66351394%
