Answer :
Answer:
Option C 41%
Step-by-step explanation:
see the attached figure to better understand the problem
we know that
The number of people who own at most three t-shirts costing more than $19 each is equal to the number of people who own one t-shirt costing more than $19 each, plus the number of people who own two t-shirt costing more than $19 each, plus the number of people who own three t-shirt costing more than $19 each
Observing the graph
The number of people who own one t-shirt costing more than $19 each is 5
The number of people who own two t-shirt costing more than $19 each is 17
The number of people who own tree t-shirt costing more than $19 each is 23
The number of people who own at most three t-shirts costing more than $19 each is
[tex](5+17+23)=45\ people[/tex]
To find out the percentage divided the number of people who own at most three t-shirts costing more than $19 by one hundred eleven people (total people that shopped in a store) and then multiply by 100
[tex](45/111)100= 40.54\%[/tex]
Round to the nearest whole number
[tex]40.54\%=41\%[/tex]

Final answer:
The question involves the application of statistical principles to determine the percentage of people who own at most three expensive t-shirts. Assuming 59% is the correct answer, this means 66 out of the 111 people surveyed own three or fewer such t-shirts. The examples in the question references demonstrate the principles of economics, but aren't directly related to the question.
Explanation:
The question is about determining the percentage of people who own at most three t-shirts costing more than $19 each from a sample of 111 people. Given that the possible percentages provided are 21% and 59%, the process involves the application of statistical principles, particularly dealing with percentages in relation to a specific sample size. This example fits into a branch of mathematics known as statistics, which deals with data analysis, collection, interpretation, presentation, and organization.
Let's assume from the reference that 59% is the correct answer, this conveys that of the 111 people surveyed, approximately 66 people own three or fewer such t-shirts. This is obtained by calculating 59% of 111, which equals about 65.49 and rounds to 66.
In the references provided, there are examples of how the cost of t-shirts affects purchasing decisions. This is related to the principles of economics which involve opportunity cost and budget constraints, but is not directly tied to answering the initial question.
