### Chap 10 Percentages: Which is a better deal? (I) National Geographic Magazines

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.

Below are the information available available.

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?

E.g. We recommend Mr Fong to purchase personnal/ subscribe through the National Geographic Store/ Online subscription/ at the newstand because, by this mode of purchase because he is going to pay ..... (describe the amount he pays for each mode of purchase, hence do a comparison)

5. When making the comparisons, what challenges do you encounter?

1. From YAP•MATT and Sandy:

1) We think that subscribing from the store is more worth it. As, if a subscription lasts for a year, the purchasing of an individual book would cost "\$7.60 x 12 = \$91.20" While the subscription only costs \$49. Which has a difference of \$42.

2) For each issue the subscription costs about \$6.33 (3 S.F). However, in the store, it only costs "\$49 ÷ 12 = \$4.03 (3S.F) and there is a difference of \$2.03, thus buying from the store is better.

3)
(a) If one buys from "Emit Asia", one saves "\$11 - \$6.03 = \$4.97"
(b) One saves 49.7%.

2. 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?

Ans: To subscribe from the store is a better deal . For the buying from the store, we will need to buy 12 issues , thus 7.60 x 12 = \$91.2 but the subscription is only \$49 so it is 46.3% (3 S.F) cheaper.

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?

Ans: The subscriber would pay 6.33 (3 SF) for each issue. It is giving a better deal if the buyer is going to the store to buy but a worse off deal if the buyer is subscribing from 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?

(a) One issue is \$6.33 (3SF) So we would save 11 - 6.33 = 4.67 SGD.

(b) 12 issue = 11 x 12 = 132 so we would save 42.2% if we subscribe instead.

We recommend Mr Fong to subscribe through the National Geographic Store because, by this mode of purchase because he is going to pay \$76 for subscription through newsstand and the website , \$11 if going to the newsstand to buy individual issue which is \$132 for a year, \$49 if subscribe through the store, hence subscribing through the store would be the cheapest.

5. When making the comparisons, what challenges do you encounter?
I encountered a lot of challenges like time management, difficulty changing tabs from the store,newsstand and the websites and this blog as it is tiring to remember the prices properly.

5. 1. At the National Geographic Store, the better deal would be subscribing from the store.
If we buy personally, 12 issues will cost \$\$91.20 whereas, through subscription, we will be paying \$49 only. We would save \$42.20

2. At the National Geographic Website, it charges \$76 for 12 issues.
The subscriber will be paying for \$6.33 per issue.
Whereas, if we subscribe at the store, it would only cost us \$4.08 per issue.
Hence, subscribing at the store will be a better deal.

3. Based on the information at "EmitAsia",
(a) The newsstand price is \$11.
Hence, we would be saving (\$11-\$6.33 =) \$4.67 for each issue if we subscribe online.

(b) Discount (in percent) if purchased through subscription = \$4.67/\$11 x 100%
= 42.5% (3SF)

4. Compare the prices obtained from above and you should be able to find out which one gives the best deal :)

6. Some points to note...

1. Price to be given up at 2 decimal places.

2. As of the challenges in the recommendation, you might like to look at the freebies that come with the subscriptions :)
Sometimes, this made the comparison challenging. Depending on the indivudual's needs, one may find it worth paying slightly more in order to get the free gift. However, there are also people who do not require that, then the free gift would no longer be a part for consideration.
