L’Oréal Paris is organizing a promotional activity for the Derma Genesis anti-aging product line:an SMS (Short Message Service) campaign offering Derma Genesis night cream for $15 instead of $20.The 3000 recipients of this message will be extracted from the aufeminin database.Recipients will include only women over 40 years old who have agreed to be contacted by SMS on behalf of the site’s partners.
The project’s invoice components are:
- Address rental and transmission:$0.40,taxes included
- Technical fees:$250 per extraction
- Extraction cost:$50 per criterion
Knowing that the profit margin of Derma Genesis night cream at the $15 promotional price is $5,what do you think the return rate will have to be in order to show a profit?
1.
7.33%
2.
10.33%
3.
12.33%
4.
14.33%
目前只知道这个campaign的成本是0.4×3000+250+50×3=1600元,

好像只有两个criteria:>=40 years old, agreed to be contacted
所以成本应该是 0.4×3000+250+50×2 = 1550.
这样就是 1550 /5 /3000 = 10.33%.
不知道你怎么会觉得3个criteria呢?
yes, this should be correct.
1600/5=320
320/3000=0.10667
so the answer should be 3.
