Final answer:
The percent measurement error of the actual weight is 45.71%. Hence the correct answer is option A
Step-by-step explanation:
To find the percent measurement error, we need to calculate the difference between the actual weight and the listed weight, divide it by the actual weight, and then multiply by 100 to get a percentage. In this case, the difference is 58 - 40 = 18 ounces. The percentage measurement error is therefore (18 / 40) * 100 = 45%. Therefore, the correct answer is option a) 45.71%.
