Postal Letter

Can you show me how to do this problem?

The forever Stamp features the Liberty Bell Image and will always be aviable at the price of a first-class mail stamp at the time its bought. In April 12, 2007 the post office, started offering it @ 41cents. The stamp can be used as soon as its bought but the price won't change till May 14,2008.Its been suggested that u should stock up on these 41 cents stamps to avoid price hikes in postage in the future. Juan thinks the USA postal rate will increase 4rm 41cents to 44 cents in May 2008. He sends 30 billing statements per month. He plans 2 buy enough stamps 2 cover sending all of his statements for the 12 months beginning May 08 - May 09. What % of his postage costs will he save by buying the stamps be4 the price increase? Round ur answer to the nearest 1000th. Can you give me two ways of solving this problem. I already have one and can't think of another. thank you very much and I'll pick a best answer. My answer 41*30=12.30 & 44*30=13.20 then 13.20-12.30=.90 .90is7%of12.30

1. The percentage saved will be the same no matter how many statements are sent per month. All postages will be $0.44. Juan will have paid $0.41 per stamp. He will therefore have saved $0.03 per stamp. 3/44*100=6 36/44 or 6 9/11% = 6.818181...% Or 7% as you have rounded it off.
