Total a purchase order without a helper column
SUMPRODUCT multiplies quantity by cost row for row and adds it all up in a single formula — no line-total column needed.
Task:
You work in procurement at a manufacturing company, checking a supplier's invoice against the purchase order before it gets approved for payment. The order has four line items, each with its own quantity and unit cost, and nobody wants a helper column of line totals cluttering the sheet just to get one number. Work out the total cost of the order in B6 using a single SUMPRODUCT formula.
