{primary_keyword} Formula and Mathematical Explanation

The core calculation behind a {primary_keyword} is straightforward:

  • Weekly Gallons = Miles per Week ÷ MPG
  • Weekly Cost = Weekly Gallons × Price per Gallon
  • Monthly Cost = Weekly Cost × 4

Below is a table of variables used in the {primary_keyword}.

Variable Meaning Unit Typical Range
Miles per Week Distance driven each week miles 100‑1000
MPG Vehicle fuel efficiency miles/gallon 10‑60
Price per Gallon Current gasoline price $/gallon 2.00‑5.00

Practical Examples (Real-World Use Cases)

Example 1

John drives 300 miles per week, his car gets 30 MPG, and gas costs $3.20 per gallon.

  • Weekly Gallons = 300 ÷ 30 = 10 gallons
  • Weekly Cost = 10 × 3.20 = $32.00
  • Monthly Cost = $32.00 × 4 = $128.00

John can expect to spend about $128 each month on fuel.

Example 2

Maria commutes 150 miles weekly, her hybrid gets 50 MPG, and gas is $2.85 per gallon.

  • Weekly Gallons = 150 ÷ 50 = 3 gallons
  • Weekly Cost = 3 × 2.85 = $8.55
  • Monthly Cost = $8.55 × 4 = $34.20

Maria’s monthly fuel expense is roughly $34.
