Conceptual connection: if gilmore's estimate of bad debts is correct (2.2% of credit sales) and the gross margin is 20%, by how much did gilmore's income from operations increase assuming $150,000 of the sales would have been lost if credit sales were not offered?

increase in income = $18736

Explanation:

solution

we consider here 2 case

case 1 is

Credit Sales with bad debt estimation @ 2.2%

and

Case 2 is

Cash Sales only

so as in both the cases we are indifferent towards cash sales of $135000 as Gilmore would earn the same margin and there is no bad debt scenario.

so in case 1  gross margin is  

Gross Margin = 20% of 512000

Gross Margin  = $102400

and

Bad Debt Estimation @ 2.2% is  = $11264

so Net Margin =  $102400  -$11264  =

Net Margin =  $91136

and

in case 2 is

as company have gone for all cash sales then it will able to sell $150000 less

so cash Sales =  512000 – 150000

cash Sales = $362000    

and

Margin = 20% of 362000

Margin = $ 72400

so that  increase in income from operations by selling on credit is

increase in income from operations by selling on credit = 91136 - 72400

increase in income = $18736
