Answer:
22.459 pounds of wood
Step-by-step explanation:
Total amount of wood in store = amount of pine wood purchased + amount of cedar in the store
Total amount of wood in store = 13.145 pine wood + 16.903 cedar wood
Total amount of wood in store = 30.048 pounds of wood
If acme lumber had sold 7.589 pounds of lumber after 6 months, the amount of pounds of woods that the company have left to sell = Total amount in store initially - amount sold after 6 months

The amount of pounds of woods that the company have left to sell = 22.459 pounds of wood
