A luxury pen costs £12.75, and the engraving fee is £0.85 per pen.
If a company orders 24 pens, what is the total cost, including engraving for each pen?
(Hint: You'll need to multiply both the pen price and engraving fee by the quantity, then add them.)
Pen cost: 12.75 × 24 = £306.00
Engraving: 0.85 × 24 = £20.40
Total cost = £306.00 + £20.40 = £326.40
