AlexFokin [52]

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 :

$1\times 231 =231 sandwiches$

A single sandwich is made up of 2 bread slices , Then bread slices in 231 sandwiches will be :

$231\times 2=462$

Each bread slice is applied with 0.0500 ounce of mayonnaise.

Then 462 bread slices will have :

$462\times 0.0500 ounces=18.48 Oz$

1 bread loaf = 13 bread slices

Then breads loves in 462 bread slices :

$\frac{462}{13}=35.54\approx 36$

36 loaves of bread and 18.48 ounces of mayonnaise are needed to make all of the sandwiches.
