23. Eva estimates that 475 songs will fit on her MP3 player. The actual amount of songs that it fits is 380. Find the percent error.

Explanation
The percent error can be found by taking the absolute difference between the estimated and actual values, dividing it by the actual value, and then multiplying by 100. In this case, the absolute difference is 475 - 380 = 95. Dividing 95 by 380 gives 0.25, and multiplying by 100 gives 25%. Therefore, the percent error is 25.25%.
