Answer 2

Calculation of Initial Amount of Gasoline

To calculate the initial amount of gasoline at the gas station, we need to follow the given information step by step.

1. On the first day, 7/25 of the total gasoline was sold. 2. On the second day, 1/3 of the remaining gasoline was sold. 3. After these two days, there was 4.4/5 (or 22/25) of the total gasoline left at the gas station.

Let's calculate the initial amount of gasoline using these steps:

Step 1: Calculate the amount of gasoline remaining after the first day: - Let's assume the initial amount of gasoline is x. - On the first day, 7/25 of the total gasoline was sold, so the amount remaining is x - (7/25)x.

Step 2: Calculate the amount of gasoline remaining after the second day: - On the second day, 1/3 of the remaining gasoline was sold, so the amount remaining is (x - (7/25)x) - (1/3)(x - (7/25)x).

Step 3: Calculate the amount of gasoline remaining after both days: - After these two days, there was 22/25 of the total gasoline left, so we have the equation (x - (7/25)x) - (1/3)(x - (7/25)x) = (22/25)x.

Now, let's solve this equation to find the initial amount of gasoline:

(x - (7/25)x) - (1/3)(x - (7/25)x) = (22/25)x

Simplifying the equation:

(18/25)x - (1/3)(18/25)x = (22/25)x

(18/25)x - (6/25)x = (22/25)x

(12/25)x = (22/25)x

12x = 22x

10x = 0

Since we have reached an inconsistent equation (0 = 10), it means there is no solution that satisfies the given conditions. Therefore, it is not possible to determine the initial amount of gasoline at the gas station based on the information provided.
