Answer:
36 loaves of bread and 18.48 ounces of mayonnaise are needed to make all of the sandwiches.
Explanation:
Number of slices of ham = 231
Given that each sandwich has 1 slice of ham.
Then 231 slices of ham will be in :
A single sandwich is made up of 2 bread slices , Then bread slices in 231 sandwiches will be :
Each bread slice is applied with 0.0500 ounce of mayonnaise.
Then 462 bread slices will have :

Percent error is the difference between the measured and known value, divided by the known value, multiplied by 100%.
So first, we take our measured value, .299 cm, minus our known value, .225 cm.
.299 cm - .225 cm=.004 cm
Next, we divide that by our known value
Finally, multiply your answer by 100
.0177777778 x 100= 1.77777778 %
Round to three significant figures, and you're done.
=1.78 % error
