Answer:
1. 45.5%
2. 13.3%
3. 7.2%
Explanation:
The formulas and calculations are shown below:
1. Gross margin = (Sales - cost of sales) ÷ (sales) × 100
= ($10.1 million - $5.5 million) ÷ ($10.1 million) × 100
= ($4.6 million) ÷ ($10.1 million) × 100
= 45.5%
Gross profit = Sales - cost of sales
2. Operating margin = (Gross profit - selling, general and administrative expenses - research and development - annual depreciation charges) ÷ (sales) × 100
= ($4.6 million - $460,000 or $0.46 million - $1.4 million - $1.4 million) ÷ ($10.1 million) × 100
= ($1.34 million) ÷ ($10.1 million) × 100
= 13.3%
Operating income = Gross profit - selling, general and administrative expenses - research and development - annual depreciation charges
3. Net profit margin = (Operating income - taxes) ÷ (sales) × 100
= ($1.34 million - $0.6097 million) ÷ ($10.1 million) × 100
= ($0.7303 million) ÷ ($10.1 million) × 100
= 7.2%
The income tax expense = Operating income × income tax rate
= $1.34 million × 45.5%
= $0.6097 million
