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

Yes, I agree with this because firstly ... there is a pressure of studies and then secondly... there is another stress of hormonal changes happening inside our body which doesn't allow our mind to rest !...so they start finding some new people to talk to or find some new things to do so that they be relieved from this stress for at least some time !!...

have a great day!
