Answer 2

Calculation of Gasoline Consumption

To calculate the amount of gasoline consumed during the trip to the dacha, we need to subtract the amount of gasoline remaining in the tank from the total amount of gasoline added.

Given information: - Initially, there were 10 liters of gasoline in the car's tank. - At the gas station, an additional 30 liters of gasoline were added. - When the car arrived at the dacha, there were 27 liters of gasoline remaining in the tank.

To find the amount of gasoline consumed, we can subtract the remaining amount from the total amount added:

Gasoline consumed = Total amount added - Remaining amount

Gasoline consumed = 10 liters + 30 liters - 27 liters

Gasoline consumed = 13 liters

Therefore, 13 liters of gasoline were consumed during the trip to the dacha.
