Percent error is calculated using
((Actual - predicted) / actual) * 100
In this case, the actual value of the number of pages he read is 20. The expected value was 23. So simply plug in:

Answer:
45.1
Step-by-step explanation:
The original amount is 82
But the wrong amount is 45
So we will have to calculate the percentage for the error
82-45
37
So %error= 37/82 ×100
=3700/82
=45.121~45.1( to nearest tenth)
So the final answer is 45.1%
