In a popular online role playing game, players can create detailed designs for their character's "costumes," or appearance. Michael 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.
215 visitors purchased no costume.
12 visitors purchased exactly one costume.
3 visitors purchased more than one costume.
If next week, he is expecting 1800 visitors, about how many would you expect to buy more than one costume? Round your answer to the nearest whole number.
3 of 215 + 12 + 3 purchased more than one costume
3 of 230 purchased more than one costume.
Proportion:
3 / 230 = x / 1800
Cross multiply
3 ∙ 1800 = 230 x
5400 = 230 x
x = 5400 / 230 = 23.478261
x = 23 rounded to the nearest whole number
