I want to take a price and and increase it by a percentage. However, we also
rounded to the nearest nickel. If the cents was 3.75 we would multiply it by
3% that would make the price 3.87 then we would round it to 3.90. If the
price was 3.71 after the increase then we would round it to 3.70. Any
suggestion how to automat this so we don't have to go and manually change
each price?

Thanks for the help
