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.

yes

Step-by-step 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

We conclude that will  rent be at the end of this year 937.125$.

Step-by-step explanation:

We know that we have budgeted $850 per month for rent. Your landlord has just informed you that your rent is being raised by 5% now and another 5% on December 1st.

We calculate

now, we get

We conclude that will  rent be at the end of this year 937.125$.
