Flextrola, Incorporated, an electronics systems integrator, is planning to design a key component for its next$-$generation product with

Solectrics. Flextrola will integrate the component with some software and then sell it to consumers. Given the short life cycles of such

products and the long lead times quoted by Solectrics, Flextrola only has one opportunity to place an order with Solectrics prior to the

beginning of its selling season. Flextrola's demand during the season is normally distributed with a mean of $1,200$ and a standard

deviation of $700.$ Use Table $13\mathrm{.}4.$

Solectrics' production cost for the component is $$50$ per unit, and it plans to sell the component for $$70$ per unit to Flextrola. Flextrola

incurs essentially no cost associated with the software integration and handling of each unit. Flextrola sells these units to consumers

for $$123$ each. Flextrola can sell unsold inventory at the end of the season in a secondary electronics market for $$45$ each. The existing

contract specifies that once Flextrola places the order, no changes are allowed to it$.$ Also, Solectrics does not accept any returns of

unsold inventory, so Flextrola must dispose of excess inventory in the secondary market.

Note: If a part of the question specifies whether to use Table $13\mathrm{.}4,$ or to use Excel, then credit for a correct answer will depend on

using the specified method.
