Franklin purchased 8.67 pounds of fruit. He bought a 2.8 pound of pineapple, 3.09 pound of cherries, and some bananas. How many pounds of banana did he buy

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.
