Interest earned can be calculated using the following equation:
I = P{(1+r/n)^t-1}
Where, I = Interest earned, P = Amount deposited, r= Interest rate (annual) = 3.5% = 0.035, n = 365 days, t= time in days = 55 days (deposit and withdrawing days are not counted).
Therefore,
I = 975{(1+0.035/365)^55 -1 ) ≈ $5.16
