Answer 2

Problem Analysis

We are given that there was initially 20 liters of gasoline in a canister. After pouring out several liters, the amount of gasoline remaining in the canister is four times the amount poured out. We need to determine how many liters of gasoline are left in the canister.

Solution

Let's assume that x liters of gasoline were poured out of the canister. According to the problem statement, the amount of gasoline remaining in the canister is four times the amount poured out. Therefore, the amount of gasoline remaining is 4x liters.

We can set up the following equation to represent the given information:

20 - x = 4x

To solve for x, we can simplify the equation:

20 = 5x

Dividing both sides of the equation by 5, we get:

x = 4

Therefore, 4 liters of gasoline were poured out of the canister. To find the amount of gasoline remaining in the canister, we substitute x = 4 into the equation:

20 - 4 = 4 * 4

16 = 16

So, there are 16 liters of gasoline remaining in the canister.

Answer

There are 16 liters of gasoline remaining in the canister.
