Ineed solving this and getting the right answer. i got the answers 3.7854 changed to 3.79, and another answer which is 3.7878

Step-by-step explanation:

I wonder if it wants 3.80 per gallon?

Perhaps the imperial value which would have been 4.50 per gallon which is an imperial gallon (used in Canada). It's hard to tell. I would have thought 3.78 should be more than close enough.

$3.79/$4.55

Step-by-step explanation:

1. How many liters in a gallon: 3.79 l (US), 4.55 l (Imp)

2. Cost of gas/gallon: 3.79 liter * $1/liter = $3.79 (US), $4.55 (Imp)

From what you say, using the US gallon, since both answers round to the same number (since there is no currency below the cent), it wouldn't matter too much. Also, unit conversions should not lead to different answers.
