Quality Products uses a JIT system to manufacture trading pins for the Hard Rock Café. The standard cost per pin is $2 for raw materials and$3 for conversion costs. Last month Quality recorded the following data:

$$\begin{array}{|l||r||l||rr|} \text { Number of pins completed } & 4,000 \text { pins } & \text { Raw material purchases } & \$ 9,500 \\ \text { Number of pins sold } & 3,300 \text { pins } & \text { Conversion costs } & \$ 8,000 \end{array}$$

Requirement

1. Use JIT costing to prepare journal entries for the month, including the entry to close the Conversion costs account.
