Question

PLEASE ANSWER ASAP!!!!!!!!!!!!!!!!!!!!!

Yesterday, I put 10 gallons of gas in my car and I paid $30. A couple hours after, I went back to the gas station with my dad’s car and I put 6 gallons and I paid $18.

Answer 1

Yes it is proportional, say that it cost $3 per gallon. So for ten gallons of gas it is $30 and for 6 gallons it is $18 because 6x3=18
