Question

In December of 2003, the average price for a gallon of regular gas in the United States was $1.50.

b. Is the relationship between number of gallons and cost proportional? Explain. ​

Answer 1

yes

Explanation:

because the cost stays the same and you would multiply blank gallons of gas by 1.50 every time so it is proportional. For example: it would be $1.50 to 1 gallon, $3 to 2 gallons, $4.50 to 3 gallons and would keep going like that, adding the same amount every time
