Question

the venn diagram below shows the data collected at a sandwich shop for the last six months with respect to the type of bread people ordered (sourdough or wheat) and whether or not they got cheese on their sandwich. use this data to answer the following question: if they serve 100 sandwiches at lunch on a particular day, how many orders with sourdough should be prepared without cheese? without cheese 15% 10% 55% with cheese 20%

Explanation:

Step1: Identify the relevant percentage

From the Venn - diagram, the percentage of sourdough bread without cheese is 55%.

Step2: Calculate the number of sandwiches

We know the total number of sandwiches is 100. To find the number of sourdough sandwiches without cheese, we use the formula: Number = Percentage×Total. So, the number of sourdough sandwiches without cheese is 55% of 100, which is $0.55\times100$.
$0.55\times100 = 55$

Answer:

55
