Answer:
Total cash flow $54,613
Step-by-step explanation:
The computation of the year 4 cash flow is given below:
Selling price of equipment $6,920
Book value at year 4 end $5,460
Capital gain $1,460
Tax on capital gain at 21% $306.6
So, net cash flow from the sale of equipment
= $6,920 - $307
= $6,613
Now year 4 cash flow is
Annual operating cash flow $42,000
Release of working capital $6,000
Net cash flow form sale of equipment $6,613
Total cash flow $54,613
