Calculate a weighted average price

A business sells 20 units at 10 each and 30 units at 15 each. What is the average selling price per unit?

Profitability bridge

Trace quantities through revenue, cost, profit, and ratio

Revenue
Units × selling price
Direct cost
Units × defined direct unit cost
Gross profit
Revenue − direct cost
Margin
Gross profit ÷ revenue
Markup
Gross profit ÷ cost

Margin and markup use the same profit numerator but different denominators. Keeping that bridge visible prevents a plausible but mislabeled percentage.
