Answer: A. 8.8%
Explanation:
Percent Error Formula: approximate error - actual value divided by actual value (Approximate-Actual/Actual). After those steps are completed, multiply by 100 to make it a percentage form.
0.365 - 0.400 = -0.035
-0.035 / 0.400 = 0.0875
0.0875 * 100 = 8.75%
8.75% rounded to the nearest tenth is 8.8%
