Answer:
2.78 pounds
Step-by-step explanation:
Set up an equation. Represent the bananas bought with x.
Total pounds of fruit = pineapple + cherries + bananas
8.67 pounds = 2.8 pounds + 3.09 pounds + x bananas
Combine like terms.
8.67 = 5.89 + x
Subtract 5.89 from both sides.
2.78 = x
He bought 2.78 pounds of bananas.
