For example, if you choose 1024MB of traffic, 1200 minutes of voice and 600 SMS/MMS messages, the background will calculate the estimated consumption (the estimated usage charge standard is calculated according to the ladder price standard) and the average unit price of the current business package (the average price of the business package is calculated according to the usage) according to the business volume of each service you choose, and the sum of the three business consumption is the monthly package consumption you are about to order. Finally, the calculation results are rounded to two decimal places, that is, accurate to minutes. (Unit: Yuan)

The specific calculation method is as follows:

Flow:1g (1024/MB; ) Traffic price =100 * 0.15+400 * 0.07+524 * 0.05 = 69.2 yuan, so the average unit price of traffic at this time = 69.2 yuan/10 yuan. ?

Call:1200min = 500 * 0.15+500+0.12+200+0.08 = 15 1 yuan, then the average voice unit price at this time is =/kloc. ?

SMS/MMS: 600 pieces = 50 * 0.1+450 * 0.06+100 * 0.05 = 37 yuan, so the average unit price of SMS/MMS at this time = 37 yuan /600 minutes =0.062 yuan/piece. ?

So the total monthly fee you ordered is 69.2+151+37 = 257.2 yuan, and the 20% discount price is 205.76 yuan.
