Can someone help me to calculate Cash Flow statement?

A. Income Statement Data for 20XX:

Units produced and sold = 420

Sales ($80 per unit selling price) = $33600

Cost of goods sold ($30 per unit, all variable costs) = $12600

Labor = $0 (Mr. and Mr. Lee were the only ones working and did not pay themselves)

Advertising fees =$2000

Bank fees = $150

Phone/internet = $1200

Shipping ($3 per unit) = $1260

Utilities = $900

Office supplies = $800

Interest expense on note payable = $350

Depreciation expense (straight line) = $800

My answer:

Particulars	Amount
Sales	$ 33,600.00
Cost of Goods Sold	$ 12,600.00
Gross Profit	$ 21,000.00
Less Operating and Admin. Expenses
Advertising	$ 2,000.00
Bank Fees	$ 150.00
Phone/Internet	$ 1,200.00
Shipping	$ 1,260.00
Utilities	$ 900.00
Office Suppies	$ 800.00
EBITDA	$ 14,690.00
Depriciation	$ 800.00
EBIT	$ 13,890.00
Less
Interest on Notes Payable	$ 350.00
EBT	$ 13,540.00
Less Tax at 26%	$ (3,520.40)
Net Profit	$ 10,019.60

Now I need to calculate cash flow

B. Proceeds from sale of equipment = $3000. The equipment originally cost $1000 and had accumulated depreciation of $200.

Purchase of equipment = $1600 (The machine is purchased on the last day of 20XX so no depreciation expense is recorded.)

Repayment of note payable = $5000

Consider any data relevant from the income statement.
