Answer 2

Calculation of Gasoline Sold

To calculate the amount of gasoline sold in the third hour of operation and the total amount sold in three hours, we can follow the given information.

In the first hour, 80 liters of gasoline were sold.

In the second hour, 40 liters more than the first hour were sold, so a total of 80 + 40 = 120 liters of gasoline were sold.

In the third hour, 50 liters less than the combined amount sold in the first two hours were sold. Therefore, the amount sold in the third hour can be calculated as (80 + 40) - 50 = 70 liters of gasoline.

Answer:

- Amount of gasoline sold in the third hour: 70 liters - Total amount of gasoline sold in three hours: (80 + 40) + 70 = 190 liters
