Concept explainers
a.
The cost of each archived article for which the fee is paid.
For viewing more than 25 and less than 30 archived articles the cost of each archived article is $9.83 and for viewing more than 30and less than 33 archived articles the cost of each archived article is $2.75.
Given: It is given that a magazine allows an online subscription which allows to view 25 archived articles free. And to view 30 archived articles the pay is $49.15. Also to view 33 archived articles the pay is $57.40
Calculation:
Since, to view 25 archived articles there is no cost to pay. And to view 30 archived articles the fee to be paid is $49.15. Therefore, the cost to view 30-25=5 archived articles to view is $49.15.
It means that,
Hence, when viewing more than 25 archived articles and less than 30 archived articles the cost of each archived article is $9.83.
Similarly, the cost for 30 archived articles to view is $49.15 and the cost for 33 archived articles to view is $57.40. Therefore, the cost to view 33-30=3 archived articles to view is evaluated as,
Hence, when viewing more than 30 archived articles and less than 33 archived articles the cost of each archived article is $2.75.
