Answer:
The value of the marginal rate of technical substitution when K = 30 and L = 15 is 1.285
Explanation:
MRTS_KL = MP_L/MP_K
= (7K + 10L - L^2)/7L
= (7*30 + 10*15 - (15)^2)/7*15
= 1.285
Therefore, The value of the marginal rate of technical substitution when K = 30 and L = 15 is 1.285

Answer: e. 8.61%
Explanation:
This is a perpetual bond so the price is calculable by;
Price = Coupon / Yield to Maturity
Coupon = 7.75% * 1,000

900 * YTM = 77.50
YTM = 77.50/900
= 8.61%
