Interpret complex expressions by treating meaningful sub-expressions as single units.
Select the expression part that answers a specific context question
Problem
For \(n\) items with a \(\$40\) base fee and a cost of \(\$6~\text{each}\), identify the part of \(1.08(40~+~6n)\) that represents the subtotal before tax.
Big Picture
What this problem is really about
To locate a requested quantity inside a larger expression, follow the operations in their actual order. We’ll identify the complete amount built from the fixed and per-item costs, then separate that amount from the outside multiplier that acts afterward. The boundary between those stages isolates the pre-adjustment subtotal without dropping either of its components.
