In order to encourage residents to save water, if the monthly water consumption of a certain place in a city does not exceed 10 ton (including 10 ton), the unit price of water fee is 1.3 yuan, and if it exceeds 10 ton, a residential area in 2 yuan will pay/kloc-0 in May.

Answer:

First of all, the most basic water fee is the minimum water fee:1.3 *10 *100 =1300 yuan.

Excess 1682- 1300=382 yuan.

Excess water 382/2= 19 1 ton.

Since the minimum possibility is required, everyone who uses more than 10 tons of water should use 15 tons.

Suppose that user X used 15 tons (15-10) * x =1682-11.

The results show that X=38.2, so the water consumption of 39 households exceeds 10 ton.

Do not exceed 100-39=6 1 (household)

A: The monthly water consumption may not exceed 10 tons, and at most there may be 6 1 household.
