Calculation of Initial Amount of Gasoline

To calculate the initial amount of gasoline at the gas station, we can use the information provided about the sales on the first and second days and the remaining amount after the second day.

1. Sales on the First Day: 7/25 of the total gasoline was sold on the first day. 2. Sales on the Second Day: 13/20 of the remaining gasoline was sold on the second day. 3. Remaining Amount: After the second day, 4 4/5 of the gasoline was left.

Let's calculate the initial amount of gasoline using this information.

First, we'll calculate the amount of gasoline remaining after the first day's sales, and then we'll use that to calculate the initial amount of gasoline.

Calculation Steps

1. Calculate the Amount of Gasoline Remaining After the First Day's Sales: - Let's assume the initial amount of gasoline is represented by the variable G. - The amount of gasoline remaining after the first day's sales is given by: G - (7/25)G = (18/25)G.

2. Calculate the Amount of Gasoline Remaining After the Second Day's Sales: - The amount of gasoline remaining after the second day's sales is given by: (18/25)G - (13/20)(18/25)G = (7/20)(18/25)G.

3. Calculate the Initial Amount of Gasoline: - The remaining amount after the second day is given as 4 4/5, which can be represented as 24/5. - So, we have: (7/20)(18/25)G = 24/5.

Let's solve for G to find the initial amount of gasoline.

Calculation

(7/20)(18/25)G = 24/5

G = (24/5) / ((7/20)(18/25))

G = (24/5) / (63/500)

G = (24/5) * (500/63)

G = 9600 / 63

G = 152.38 tons (approximately)

Answer

The initial amount of gasoline at the gas station was approximately 152.38 tons.
