Question

Gasoline costs $2.79 per gallon Is the number of gallons proportional to the total cost

Answer 1

I don't think it's proportional, because in order for a question to be a proportional question has/could be to be like this:

Gasoline costs $2.79 per 2 gallon. How much will it cost for 8 gallon. Then, we cross multiply and all to find the answer.
