The Cost of Sales is:
= $72,000.
Explanation:
a) Data and Calculations:
Turnover = $180,000
Gross profit margin = 60%
Net profit margin = 22%
Gross profit margin = Gross profit/Turnover * 100
60% = Gross Profit/$180,000 * 100
Therefore, the Gross Profit = $180,000 * 60%
Gross Profit = $108,000
Cost of sales = Turnover - Gross profit (100% - 60%)
Cost of sales = $180,000 - $108,000
= $72,000
Alternatively, Cost of Sales:
= $180,000 * (100% - 60%)
= $72,000
