Final answer:
The total amount to be classified and expensed as research and development in 2014 is $5,007,500.
Step-by-step explanation:
The total amount to be classified and expensed as research and development (R&D) in 2014 is $5,007,500. This includes the costs of laboratory research aimed at the discovery of new knowledge ($4,925,000), the costs of testing prototype and design modifications ($712,500), and the costs of quality control during commercial production, including routine testing of products ($485,000).
The purchase of research facilities with an estimated useful life of 20 years but no alternative future use ($7,360,000) would not be classified as research and development expense but treated as a separate expense.
