I suggest taking the estimated total of 115$ and convert it to 1 percent by dividing it by 100 to get 1.15$.

First you need to answer this question: 82.5 is what percent of 115? Then you need to subtract what you get from 100.

You could then multiply your 1% by each of your answer choices and which ever one that when added with the actual amount spent (82.50) equals 115 is the answer.

im confused??
welshfella
  • welshfella
first work out 115 - 82.5 Then as a fraction the error is this difference / 115 The percentage error is this value times 100.
jchick
  • jchick
Now subtract from 100

Therefore your answer is A
welshfella
  • welshfella
the error as a fraction is (115 - 82.5) / 115 Multiply this by 100 to give you the answer

I know and understand he showed you a better way to do it anyway. That is the more formal version. However I showed you one of the quick ways to do it. Both ways end up at the same place and both are viable as solutions. btw @welshfella I am going to fan you because maybe sometimes you can straighten out the more formal versions of solving problems. Having gotten my doctorate in math I just do it the quick way lol.
