Answer 2

Problem Analysis

To solve this problem, we need to determine the initial amount of gasoline in the fuel tank before the trip. We are given the following information: - Before the trip, an additional 39 liters of gasoline were added to the tank. - During the trip, 49 liters of gasoline were consumed. - After the trip, there were 27 milliliters of gasoline left in the tank.

We can solve this problem by setting up an equation and solving for the initial amount of gasoline in the tank.

Solution

Let's assume the initial amount of gasoline in the tank is x liters.

During the trip, 49 liters of gasoline were consumed, so the amount of gasoline remaining in the tank after the trip is x - 49 liters.

After the trip, there were 27 milliliters of gasoline left in the tank, which is equivalent to 0.027 liters.

Therefore, we can set up the equation:

x - 49 = 0.027

To solve for x, we can add 49 to both sides of the equation:

x = 0.027 + 49

Calculating the right side of the equation:

x = 49.027

Therefore, the initial amount of gasoline in the tank was 49.027 liters.

Answer

The initial amount of gasoline in the fuel tank was 49.027 liters.
