If 30 gallons of oil cost $9.60, how much will 45 gallons cost at the same rate?

  1. $10.80

  2. $12.60

  3. $14.40

  4. $16.80

The correct answer is: $14.40

To find the cost of 45 gallons of oil at the same rate, you first need to determine the price per gallon based on the given information. If 30 gallons cost $9.60, you can calculate the cost per gallon by dividing the total cost by the number of gallons: Price per gallon = $9.60 / 30 gallons = $0.32 per gallon. Next, to find the cost for 45 gallons, you multiply the price per gallon by the number of gallons: Total cost for 45 gallons = 45 gallons * $0.32 per gallon = $14.40. This calculation shows that at the same rate, 45 gallons of oil will cost $14.40. Thus, the correct answer reflects the proper calculation of the rate and quantity, leading to the conclusion that the cost for 45 gallons is accurately represented by the choice given. The other options do not align with the calculated price based on the established rate per gallon.
