Identifying Budgeting Properties in Procurement

An office manager is calculating the total cost for 12 employee 'Work-from-Home' kits. Each kit contains a web-camera costing ww dollars and a headset costing hh dollars. The manager represents the total cost using the expression $12(w + h). To itemize the budget for accounting, the manager expands this to $12w + 12h.

  1. Name the mathematical property that justifies rewriting the expression this way.
  2. State the fundamental rule this property follows when a factor is multiplied by a sum inside parentheses.
