Answer 1

[AI-generated answer — Bot GPT 3.5]

To find the percentage error, we need to calculate the difference between the predicted cost and the actual cost, and then divide this difference by the predicted cost. Finally, we multiply the result by 100 to get the percentage.

The predicted cost of the books is $30.
The actual cost of the books is $19.75.

The difference is: $30 - $19.75 = $10.25

Now, we divide the difference by the predicted cost and multiply by 100:

(10.25/30) * 100 ≈ 0.342 * 100 ≈ 34.2

Rounding 34.2 to the nearest whole number, we get the percentage error as 34%.
