I knew there was interest, pretty cool tbh, Mom got 400 from 90,000 in her bank
If your mum got 400 Bells from 90,000 Bells, then that means that leelu was correct:
'Real banks usually calculate interest based on the average you had in your account over the past month... ...my theory seemed to stand in Wild World banking.'
In that case, the equation just has to be changed a little:
Instead of O being 'Original Amount of Money', it's 'Average Amount of Money throughout the Month'.
But
when they count the money for the day I wouldn't know...
Sorry...
