Chapter 10: Percentages

Percentages: Which is a better deal? (I) National Geographic Magazines 

A. Context
The National Geographic magazine is known for its high quality photographs taken by the award-winning photographers. As a resource for budding photographers in SST, the Media Club teacher, Mr Fong is considering having the National Geographic magazines made available to students.

To make the purchase, he has to make a proposal to the department to justify that he has identified the best deal for the school. He could go to the newstand to buy the magazine every month or subscribe the magazine at the annual basis.

B. Available Information (Resources)

C. Leading Questions
Using the following format, help Mr Fong to put down his recommendation, together the necessary justifications for the best deal.

1. At the National Geographic Store, which is a better deal - To buy the magazine personally at the store or subscribe from the store? Why?

2. At the National Geographic Website, it charges $76 for 12 issues. How much does the subscriber pay for each issue? Is it giving a better or worse off deal compared to the store?

3. Based on the information at "EmitAsia",
(a) how much does one save for each issue if it is purchased through subscription?
(b) how much discount (in percent) does one actually save if purchased through subscription?

D. Recommendations

    4.I recommend Mr F. to purchase subscription of the magazine through Online subscription either at EmitAsia or Natgeo online webpage because through this subscription,he saves 42.14/33% buying through the website than newstand and saves $1.4/15 compared to the store.

  2. Siddharth & Sean

    1)Buying the package deal is better as it is cheaper compared to $49 per 12 issues and $7.50 per issue.

    2)$6.33 Better price

    42.42% saved

    4)It is recommended to buy the $49 per subscription package.

    5)There is a difference in the prices.
    6) It took us time to comprehend exactly what the website meant

  3. 1) It is better to subscribe online as in the stand, each copy is $11.00 while online it is $6.33.
    2)$6.33. it is a better deal as each individual magazine is cheaper when bought online.
    3)$4.67 is saved via online subscription. 42.45%.
    4) I recommend Mr Fong to subscribe through the National Geographic Store by this mode of purchase because he is going to pay $49 for 12 copies instead of $132(newsstand) or $76(other online deal). Since $49 per 12 copies has the best rate per single magazine.
    5)The price of a single magazine(including things like discount).
    6)For the deal of $49 for 12 copies, I do not understand what $49 is for. It does not state how many copies that would cover so i had to assume its for 12 copies.
