Susan estimated she would spend $250 on school clothes at the start of the school year. She actually ended up spending only $230
. What was her percent of error in her calculations?
1 answer:
Answer:
8.70%
Step-by-step explanation:
Percentage error = (difference between estimated value and actual value / actual amount spent) x 100
difference between estimated value and actual value = estimated value - actual amount
$250 - $230 = $20
($20 / $230) x 100 = 8.6957%
