Kretsmart anticipates its sales will grow by 10% each year for the next two years...

When sales grow and cost of goods sold (COGS) is assumed to be a spontaneous account, COGS increases proportionally with sales. In the current year, Kretsmart’s gross margin ratio is calculated as Gross Margin ÷ Sales = $55 ÷ $100 = 55% , while COGS represents 45% of sales.

Sales are projected to grow by 10% per year for two years. Therefore, projected sales for Year 2 are:

$100 × 1.10 × 1.10 = $121.00 .

Since COGS remains 45% of sales, projected COGS for Year 2 equals:

$121.00 × 0.45 = $54.45 .

Gross margin is then calculated as:

$121.00 − $54.45 = $66.55 .

Financial management forecasting techniques commonly use percentage-of-sales assumptions for spontaneous accounts such as COGS, inventory, and receivables. This method allows managers to project future income statements consistently with expected growth. Option B ($66.55) correctly reflects the projected gross margin for Year 2 under these assumptions.
