Question

In a popular online role playing game, players can create detailed

designs for their character's "costumes," or appearance. Alexander sets
up a website where players can buy and sell these costumes online.
Information about the number of people who visited the website and
the number of costumes purchased in a single day is listed below.
8 visitors purchased no costume.
340 visitors purchased exactly one costume.
28 visitors purchased more than one costume.
If next week, he is expecting 600 visitors, about how many would
you expect to buy more than one costume? Round your answer to
the nearest whole number.

Answer 1

Rounded to the nearest whole number, you might expect approximately 46 visitors to buy more than one costume.

Let's break down the information provided for the single day:

8 visitors purchased no costume.

340 visitors purchased exactly one costume.

28 visitors purchased more than one costume.

So, in total, the number of visitors who purchased costumes is

340+28=368. Now, let's calculate the proportion of visitors who purchased more than one costume:

Proportion of visitors who purchased more than one costume= Visitors who purchased more than one costume/ Total visitors who purchased costumes

Proportion of visitors who purchased more than one costume=
`(28)/(368)`

​ ≈0.0761

Now, if next week Alexander expects 600 visitors, we can estimate the number of visitors who might buy more than one costume by applying the same proportion:

Estimated visitors buying more than one costume≈0.0761×600≈45.66

Rounded to the nearest whole number, you might expect approximately 46 visitors to buy more than one costume.
