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.

Answer 1

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%.
