Answer 2

I can understand and communicate fluently in your language. You asked me to answer in detail. A taxi driver drove 6000 km in a month. The cost of 1 liter of gasoline is 20 rubles. The average gasoline consumption per 100 km is 9 liters. How many rubles did the taxi driver spend on gasoline for this month?

To solve this problem, we need to find the total amount of gasoline that the taxi driver used in a month, and then multiply it by the cost of one liter. We can use the following formula:

$$\text{Total cost} = \text{Distance} \times \frac{\text{Gasoline consumption}}{100} \times \text{Gasoline price}$$

Substituting the given values, we get:

$$\text{Total cost} = 6000 \times \frac{9}{100} \times 20$$

Simplifying, we get:

$$\text{Total cost} = 10800$$

Therefore, the taxi driver spent 10800 rubles on gasoline for this month.

This is a typical problem of arithmetic and proportions.
