Find the rule and fill in the number: 35, 28, 22, 17___ A.11, b.12, c.13 and D14 should be added on the horizontal line In order to encourage residents to save water, a city charges tap water users according to the following standards: if the monthly water consumption of each household is not more than 12 tons, the charge is RMB m per ton; if the monthly water consumption is more than 12 tons, the charge is RMB 1.5m per ton; if the monthly water consumption of a household is 32 tons, how much water fee should the user pay

Find the rule and fill in the number: 35, 28, 22, 17___ A.11, b.12, c.13 and D14 should be added on the horizontal line In order to encourage residents to save water, a city charges tap water users according to the following standards: if the monthly water consumption of each household is not more than 12 tons, the charge is RMB m per ton; if the monthly water consumption is more than 12 tons, the charge is RMB 1.5m per ton; if the monthly water consumption of a household is 32 tons, how much water fee should the user pay

Answer: C 13
35-28=7
28-22=6
22-17=5
17-13=4
The water charge for 32 tons of water consumption = 12 * m + (32-12) * 1.5m = 42m yuan
