Melissa's family is driving out of state to her grandmothers house. they know it takes 20 gallons of gas to get there, and the cost of three gallons of gasoline is $10.50.how much should the family budget to make the one- way trip

I believe the family budget to make a one- way trip will be $140 because each gallon is $3.50. You need 20 gallons to get there which is $70. You need 20 gallons to get back which is another $70. You add both and is $140. Hope this helped.

What’s your question.
