The order was for $100$ pieces at a per$-$unit price of $$281.$ The buyer collected the following costs from Ronco:

Direct Material Costs $$100/$unit

Direct Labor Costs $$50/$unit $(5$ hours$/$unit at $$10/$hour labor rate$)$

Overhead Costs $$75/$unit $($calculated at $150\%$ of direct labor$)$

Total Costs of Goods Sold $$225/$unit

Seller$$s Profit $(25\%$ of total$)$ $$56$ cost markup

Total price per unit $=$ $$281$
