Work Shown
final balance = principal*(1+interestRate*time)
3000 = x*(1+0.06*2)
3000 = 1.12x
x = 3000/1.12
x = 2,678.57142857142
x = 2678.57
Check
final balance = principal*(1+interestRate*time)
final balance = 2678.57*(1+0.06*2)
final balance = $2,999.9984
final balance = $3,000
The answer is confirmed.
