A little understanding of forum rules: Things to note when trading wealth for charm
Thread Content
Learning in the forum* District, many students have already shared their experiences. I will calculate it in detail here and share the calculation results with you. Did you notice that when you use wealth charm, 10 yuan of wealth is exchanged for 1 point of charm, and you have to pay a 5% transaction fee. I have exchanged it several times. The cost-benefit ratio of the charm value that can be exchanged for the wealth value is 11 1 11 22 2 11 32 3 10.667 43 4 10.75 53 5 10.6 64 6 10.667 (equivalent to 32 wealth for 3 charms) 74 7 10.571, so it is more cost-effective to round the handling fee to an integer value. From this point of view, it is cheaper to exchange 53 points of wealth for 5 points of charm than to exchange 74 points of wealth for 7 points of charm. Keep adding some: The cost-benefit ratio of charm value that can be exchanged for wealth is 85 8 10.625 95 9 10.555 106 10 10.6 (equivalent to 53 wealth for 5 charm) 116 11 10.545 127 12 10.58 137 13 10.538 148 14 10.57 (equivalent to 74 wealth for 7 charm) 158 15 10.533 169 16 10.56 179 17 10.529 I think this looks more intuitive, and I can know how much silver is needed. I hope it will be helpful to new students. I am also a new student and I still need to continue learning. * . This post was last edited by frankqe on 2008-1-31 10:02 ]
Among them, the cost-benefit ratio of the charm value that can be exchanged for the wealth value is 33 3 11, which is wrong. It should be 32 3. Moreover, your statement is too partial and not one-sided. The formula for exchanging wealth for charm should be: required wealth = rounded up (10* Charm value/(1-0.05)), if you want to exchange for 7 charms, the calculation is: Round up (70/0.95) = Round up (73.68) = 74
Yes, you are right, let me revise it.
Reply to the original poster, within 50, it is cheaper to exchange 158 charms for 15 charms, and it is cheapest to exchange 200 charms for 19 charms.
It is necessary to study this kind of problem carefully, which is very useful when you first enter school. You can use limited wealth to get more benefits.
