Answer: She will need 12 pint sized containers.
Step-by-step explanation:
Since, '1 quart' container contains juice = 1 quart = 0.25 gallons.
⇒ Two '1 quart' container contain the juice = 2 × 0.25 = 0.50 gallons,
Let after that she used x, ' 1 pint ' containers,
Since, 1 pint container contains juice = 1 pint = 0.125 gallons,
⇒ x ' 1 pint ' containers contains juice = 0.125x gallons,
Now, if she want to make total 2 gallon of juice,
Then, 0.50 + 0.125x = 2
⇒ 0.125 x = 1.5
⇒ x = 12
Thus, She will need 12 pint sized containers.
