Introduction

When it comes to filling up at the gas station, it's essential to know the price of gasoline per gallon. However, with various pricing charts and methods, determining the correct price can be a daunting task. In this article, we will explore a mathematical approach to finding the correct answer to a gas station's pricing chart.

Understanding the Pricing Chart

The pricing chart provided by gas station A shows the price of gasoline in terms of the number of gallons. The chart is as follows:

Gallons	Price
3	9.15
5	15.25
7	21.35

Calculating the Price per Gallon

To determine the price per gallon, we need to calculate the price per unit of measurement. In this case, we will use the number of gallons as the unit of measurement.

Let's start by calculating the price per gallon for each entry in the chart.

Calculating the Price per Gallon for 3 Gallons

To calculate the price per gallon for 3 gallons, we will divide the price by the number of gallons.

Price per gallon = Price ÷ Number of gallons = 9.15 ÷ 3 = 3.05

Calculating the Price per Gallon for 5 Gallons

To calculate the price per gallon for 5 gallons, we will divide the price by the number of gallons.

Price per gallon = Price ÷ Number of gallons = 15.25 ÷ 5 = 3.05

Calculating the Price per Gallon for 7 Gallons

To calculate the price per gallon for 7 gallons, we will divide the price by the number of gallons.

Price per gallon = Price ÷ Number of gallons = 21.35 ÷ 7 = 3.05

Analyzing the Results

As we can see from the calculations above, the price per gallon is consistent across all three entries in the chart. The price per gallon is $3.05.

Conclusion

In conclusion, by using a mathematical approach, we were able to determine the correct price per gallon for the gas station's pricing chart. The price per gallon is $3.05, which is consistent across all three entries in the chart.

If the price per gallon is $3.05, how much will it cost to fill up a 20-gallon tank?
If the price per gallon is $3.05, how much will it cost to fill up a 30-gallon tank?

Answers

To find the price of gasoline for 10 gallons, we will multiply the price per gallon by the number of gallons.

Price = Price per gallon × Number of gallons = 3.05 × 10 = 30.50

To find the cost of filling up a 20-gallon tank, we will multiply the price per gallon by the number of gallons.

Cost = Price per gallon × Number of gallons = 3.05 × 20 = 61.00

To find the cost of filling up a 30-gallon tank, we will multiply the price per gallon by the number of gallons.

Q: What is the price of gasoline per gallon?

A: The price of gasoline per gallon is $3.05, as calculated from the pricing chart provided by gas station A.

Q: How do I calculate the price per gallon?

A: To calculate the price per gallon, you can use the following formula:

Price per gallon = Price ÷ Number of gallons

For example, if the price is $9.15 and the number of gallons is 3, the price per gallon would be:

Price per gallon = 9.15 ÷ 3 = 3.05

Q: What is the cost of filling up a 20-gallon tank?

A: To find the cost of filling up a 20-gallon tank, you can multiply the price per gallon by the number of gallons:

Cost = Price per gallon × Number of gallons = 3.05 × 20 = 61.00

Q: What is the cost of filling up a 30-gallon tank?

A: To find the cost of filling up a 30-gallon tank, you can multiply the price per gallon by the number of gallons:

Cost = Price per gallon × Number of gallons = 3.05 × 30 = 91.50

Q: How do I determine the price of gasoline for a specific number of gallons?

A: To determine the price of gasoline for a specific number of gallons, you can multiply the price per gallon by the number of gallons. For example, if you want to know the price of gasoline for 10 gallons, you can multiply the price per gallon by 10:

Price = Price per gallon × Number of gallons = 3.05 × 10 = 30.50

Q: What if the price per gallon is not consistent across all entries in the chart?

A: If the price per gallon is not consistent across all entries in the chart, you may need to recalculate the price per gallon for each entry. However, in this case, the price per gallon is consistent across all three entries in the chart, so you can use the calculated price per gallon to determine the price of gasoline for any number of gallons.

Q: Can I use this method to determine the price of gasoline for any number of gallons?

A: Yes, you can use this method to determine the price of gasoline for any number of gallons. Simply multiply the price per gallon by the number of gallons to find the total cost.

Q: What if I want to know the price of gasoline for a fraction of a gallon?

A: If you want to know the price of gasoline for a fraction of a gallon, you can multiply the price per gallon by the fraction of a gallon. For example, if you want to know the price of gasoline for 0.5 gallons, you can multiply the price per gallon by 0.5:

Price = Price per gallon × Fraction of a gallon = 3.05 × 0.5 = 1.525

Q: Can I use this method to determine the price of gasoline for a negative number of gallons?

A: No, you cannot use this method to determine the price of gasoline for a negative number of gallons. The number of gallons must be a positive number, as it represents the quantity of gasoline being purchased.

Q: What if I want to know the price of gasoline for a very large number of gallons?

A: If you want to know the price of gasoline for a very large number of gallons, you can multiply the price per gallon by the number of gallons. However, you may need to use a calculator or computer program to perform the calculation, as the result may be very large.
