Answer:
   4 pounds
Step-by-step explanation:
Let b represent the pounds of bananas Mrs. Davis bought. The weight of strawberries would be (7-b) and their cost would be 4×0.50 = 2.00 per pound. Her total purchase was ...
   0.50b + 2.00(7 -b) = 8.00
   -1.50b +14 = 8 . . . . simplify
   6 = 1.50b . . . . . . add 1.50b -8
   4 = b . . . . . . . . divide by 1.50
Mrs. Davis bought 4 pounds of bananas.
