Best ResponseYou've already chosen the best response.0so the formula is change in amount/ orginal

karatechopper

Best ResponseYou've already chosen the best response.0so the change in amount is the change between 65 and 40 so 6540/original

Best ResponseYou've already chosen the best response.0and the original is 40, because u said before.

Best ResponseYou've already chosen the best response.0so if u simplify that... it is 15/40

Best ResponseYou've already chosen the best response.0and if i simplify that to work with better, it becomes 3/8

karatechopper

Best ResponseYou've already chosen the best response.0Percentage Increase or Decrease \[=\frac{amount.of.change}{original.price} \times100\]\[=\frac{NPOP}{OP} \times 100\] where NP is your new price and OP is the old price

Best ResponseYou've already chosen the best response.0okay good so OP=40 and NP=65. try and put these values into the equation i gave above and what answer do you get?

anonymous

Best ResponseYou've already chosen the best response.0so i subtract 65 40 and i get 25 then what do i do multiply with 100?

anonymous

Best ResponseYou've already chosen the best response.0well let's multiply by 100 last because all that does is change our answer to percentage. so you have 25 now you need to divide by the original price

anonymous

Best ResponseYou've already chosen the best response.0good now the last step is to times by 100
