Use the 95% rule and the fact that the summary statistics come from a distribution that is symmetric and bell-shaped to find an

81 divided by 37.5 equals 2.16, 2.16 would be equivalent to 1% so to find 100% we simbly multiply 2.16 by 100, 2.16 multiplied by 100 equates to 216, so the Baker is making 216 muffins.
If this is a word problem, put it into your own words in case of getting in trouble.
