A gas station charges its customers for gasoline at the following rates:
$5.15 per gallon up to 100 gallons
$4.55 per gallon for every additional gallon up to 300 gallons
$3.11 per gallon for every additional gallon up to a cap of 500 gallons
What is the rate per gallon a customer will pay for 75 gallons of gasoline?
$5.15
$4.55
$4.75
$3.11

For a customer purchasing 75 gallons of gasoline, the pricing tier applies to the first rate, which is **$5.15 per gallon up to 100 gallons**.

Since 75 gallons is less than 100 gallons, the rate the customer will pay is **$5.15 per gallon**.

So, the correct answer is: **$5.15**.
