Collections of accounts receivable	
$285,000	$328,900
[$51,000+($450,000*65%*80%)=$285,000]
[($450,000*65%*20)+($520,000*65%*80%)=$328,900]	
Total cash receipts	$442,500	$510,900
($157,500+$285,000=$442,500)
($182,000+$328,900=$510,900)
 Estimated cash payments for:
Manufacturing costs	$174,500	$305,000
[$102,000+($290,000*1/4)=$174,500]
[($290,000*3/4)+($350,000*1/4=$305,000)]
Selling and administrative expenses	$37,000 $37,500

Cash balance at beginning of month	$45,000	$26,000
 
Cash balance at end of month	$26,000 $154,400
(-$19,000+$45,000=$26,000)

Minimum cash balance $20,000	$20,000	
Excess (deficiency)	$6,000	$134,400
($26,000-$20,000=$6,000)
