She should buy 21 gallons of fruit juice and 7 gallons of soda.

Step-by-step explanation:

Let x be the number of gallons of fruit juice and y be the number of gallons of soda.

the answer is d

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
