Ari decided to play a gumball guessing game. She had to guess how many gumballs were in a jar. Ari guessed that there were 250 gumballs. There were actually 205 gumballs in the jar. Find Ari's percent error. Round to the nearest hundredth.
To find the percent error, we need to compare Ari's guess (250) to the actual number of gumballs (205).
First, we find the absolute difference:
|250 - 205| = 45
Then, we divide the absolute difference by the actual number and multiply by 100 to convert to a percentage:
(45 / 205) * 100 = 0.2195 * 100 ≈ 21.95
Therefore, Ari's percent error is approximately 21.95%.
