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. Well, I think it's the system of equation. There's only one way to solve the problem, as far as I know. It's your solution. If you got the solution by eliminating the variables, the other solution is using the substitution method, and vice-versa.
