Answer:
Lexicon should invest in the system. The reason why it should is shown in the explanation.
Explanation:
Give the investment is carried out, the reduction in processing time by 2 days will decrease the check outstanding by $360,000, which is calculated as average check collection daily x number of day processing time is reduced or 180,000 x2.
The opportunity cost saving from reduction in outstanding check = 360,000 x 12.3% = $44,280
The incremental benefit from investment = Opportunity cost saving - Cost of the lockbox system = 44,280 - 33,000 = $11,280.
Thus, Lexicon should invest in the system as it save the company $11,280 each year.
