Aatikah plans to buy books at a book fair she think she’ll need $30 to purchase the books she only spends $19.75 find the percent error and her prediction round your answer to the nearest whole number
A. 2%
B. 52%
C. 58%
D. 1%.
To find the percent error, we use the formula:
Percent error = (|Actual - Predicted| / Actual) * 100
Given that Actual = $19.75 and Predicted = $30, we can calculate the percent error:
Percent error = (|19.75 - 30| / 19.75) * 100
Percent error ≈ (10.25 / 19.75) * 100
Percent error ≈ 0.5189873 * 100
Percent error ≈ 51.89873
Rounding this to the nearest whole number, the percent error is 52%.
Therefore, the answer is B. 52%.
