Peter is an interior house painter. He can paint 1,650 square feet of walls with 5 gallons of paint. He is scheduled to paint a new house that will have between 3,200 and 3,400 square feet of walls. About how many gallons of paint will he need to paint the interior of the new house?

Should the answer be 20, or 10? I don't know which one, because it could be either, and more is better I can't get this question wrong

THANK YOU! Have a wonderful day
