The owners of sweet tooth bakery have determined that they need to expand their facility in order to meet their increased demand for baked goods. The decision has come down whether to expand now with a large facility or to undertake small expansion.
Management has estimated the following:

  • The demand when being high is 0.70
  • The demand when being Low is 0.30
    Profits for each alternative have been estimated:
  • Large expansion has an estimated profitability of either $80 000 or $50 000, depending on whether demand turns out to be high or low.
  • Small expansion has a profitability of $40 000 assuming that demand is low.
  • Small expansion with an occurrence of high demand would require considering whether to expand further. If the bakery expands at this point, the profitability is expected to be $70 000. If it does not expand further, the profitability is expected to be $50 000.
