well we know that $250 is 100% so lets jot that down. We now need to find out what 1% of that is. so dividing 250 by 100 would give you...two dollars and fifty cense, or 2.5.
add 2.5 with another 2.5 to get 5 buck. 5 bucks is 2% of your $250 savings and so if we do the math by adding, $255 would be a 2% increase
