Answer:
The historical cost of the debt securities available for sale was $69,670.
Explanation:
Market value of the securities = $57,320
Cumulative unrealized Loss = $12,350
Historical cost of the securities held for sale = Market Value of the Securites + Cummulative unrealized losses
Historical cost of the securities held for sale = $57,320 + $12,350
Historical cost of the securities held for sale = $69,670
Securities Held for sale are recorded at the fairmarket value and its losses are accumulated. By adding cummulative losses of security to Maerket value of security we can calculate historical cost of the security.

Answer: A. the firm could produce 3 more units of output if it increased its use of capital by one unit (holding labor constant).
Explanation:
The Marginal Rate of Technical Substitution(MRTS) is calculated as follows:
= Marginal product of labor / Marginal product of capital 
= 1 / 3
Marginal product of labor = 1
Marginal product of capital = 3
This means that if one unit of labor is used, it produces 1 unit of output. 
If one unit of capital is used however, it produces 3 units of output. 
If a firm therefore used one unit of capital and kept labor constant, it could produce 3 units out output.
