Still pissed ....

Ok, still can't help thinking about the situation with my mom, so I decided to calculate and see if I really "cheated" my mom....

Mar - $38.50, 5% GST $1.93
Apr - $37.65, 5% GST $1.88
May - $44.80, 5% GST $2.24
Jun - $36.75, 5% GST $1.84
Jul - $36.00, 7% GST $2.52

Total $10.41

Mar - $X69.04, Amt Transfered $X70.00, Extra $0.96
Apr - $X26.13, Amt Transfered $X30.00, Extra $3.87
May - $X22.50, Amt Transfered $X25.00, Extra $2.50
Jun - $X11.70, Amt Transfered $X15.00, Extra $3.30
Jul - $X85.41, Amt Transfered $X90.00, Extra $4.59

Total $15.22

So therefore, my mom should refund me

$4.81!!

Next mth, I will just transfered the EXACT amt to her, no more rounding up. If she wants to be calculative, so can I!!
