If gas cost $3.97 per gallon, what is the cost of filling a 13.8 gallon gas tank?
Do I multiply this?
Is $54.78 the correct answer?
Thank you
Yes you would multiply this. And assuming the tank is empty that is the correct answer
To find the cost of filling a 13.8 gallon gas tank at a price of $3.97 per gallon, you would indeed multiply the price per gallon by the number of gallons.
In this case, the calculation would be:
Cost = Price per gallon x Number of gallons
Cost = $3.97 x 13.8 gallons
Cost = $54.726
Therefore, the correct answer would be $54.73 (rounded to two decimal places, as the price of gas usually includes cents).
It appears that you rounded the answer to $54.78, which is slightly higher than the actual result. To double-check, you can use a calculator or perform the multiplication again to be certain.
