Okay I plans to buy books at a book fair she thinks she only dollars to purchase the books she only spends $19.75 find the percent error and her prediction around your answer to the nearest whole number

Answer 1

To find the percent error, we need to calculate the difference between the predicted cost and the actual cost, and then divide it by the actual cost.

The predicted cost is $20, and the actual cost is $19.75.

Difference = Predicted cost - Actual cost = $20 - $19.75 = $0.25

Percent error = (Difference / Actual cost) * 100

Percent error = ($0.25 / $19.75) * 100 ≈ 1.27%

Rounded to the nearest whole number, the percent error is approximately 1%.
