This activity is very interesting to play and the rewards are also very good. Ordinary balloons only need to be blown once to tie them up, while colored balloons need to be blown multiple times to tie them up. The optimal number of times for colored balloons is six times. It is recommended to exchange schoolbags for Big Krypton. The principal can choose to exchange them for snacks.
According to calculations, you can get one colored balloon every four times you blow it up. As can be seen from the figure, the optimal number of times is six times .
Regarding the cost-effectiveness of the exchange, the value of tuition fees is not considered. The converted unit price of the schoolbag is 533 pieces, and the pocket money can be directly converted into snacks, each snack is worth 25 pieces.
For most principals, the best option is to change school bags . Card points are of little significance to the little krypton principal, while the big krypton principal can choose to exchange them for snacks.
Of course, this is just a theoretical value. A lucky principal may be able to blow more times.
In addition, yellow and red balloons can also be blown up (because personal preference may be between 7 and 9 times for blowing colored balloons), so you can decide whether to blow up yellow and red balloons.
For blue and purple balloons, they only need to be blown once before being tied.
As for fair face, you can always blow up colorful balloons.
