The cost of a fully automatic moxa bed to smoke a person at a time child

I give you to calculate the cost of doing a bar, first of all, you put seven to eight columns of moxa, put a better 15:1 bar. In the market, Datang Ai Shen sells 1.2 yuan a grain, put seven it. The cost of moxa columns is 8.4 yuan

Then the cost of electricity, according to the moxa columns burning time roughly one hour, Datang Ai Shen moxibustion bed ignition time of five minutes, and then add the lifting and swinging and other features of the use of an hour of power consumption is 0.55 degrees. According to the price of commercial electricity will not exceed 50 cents.

This makes the cost of using do one person is the cost of moxa pillars 8.4 yuan + electricity 0.5 yuan. ***8.9 dollars. No more than 9 bucks.
