Answer: The family budget to make the one-way trip should be $70.

Explanation:

Given: The cost of three gallons of gasoline=$10.50

Therefore, the cost of one gallon of gasoline=
(10.50)/(3)=\$3.5

Since, they need 20 gallons for driving out of state to her grandmother’s house.

The cost of 20 gallons of gasoline =
20*3.5=\$70

Therefore, The family budget to make the one-way trip should be $70.
