Answer:
$451,000
Step-by-step explanation:
The computation of cash flows from investing activities is shown below:-
Sale of equipment $47,000
($78,000 - $31,000)
Purchase of new truck ($106,000)
Sale of land $420,000
Sale of Long-term investments $90,000
Net cash provided by investing activities $451,000
Therefore to reach the cash flows from investing activities we simply added the sale of equipment, sale of land, sale of long term investments and deduct the purchase of new truck.
