@raman707,
I'll let you do the math to figure out what the percentages are. Here are the equations you need to solve:
1st month = 1% of $345.00
2nd month = 2% of $592.00
3rd month = 2% of $609.00
4th month = 1% of $280.00
5th month = 3% of $1,020.00
6th month = 1% of $452.00
----------------------------------------
Total = (1% of $345.00)+(2% of $592.00)+(2% of $609.00)+(1% of $280.00)+(3% of $1,020.00)+(1% of $452.00)
