Prepare a direct materials purchasing plan for January, February, and March, based on the following facts.

Lana Gonzales owns a business that assembles ceiling fan units. Each fan requires one motor system and four blades. Motors cost $$45$ each, and blades are $$4\mathrm{.}00$ each.

Lana is able to reliably obtain motors as needed, and does not maintain them in inventory. However, blades are stocked in inventory sufficient to produce $40\%$ of the following month's expected production.

Planned production is as follows:

January $11,000$

February $13,000$

March $16,000$

April $12,000$

In accordance with the stocking plan, January's beginning inventory included $13,000$ blades.
