Answer:
A decrease in labor force participation rate
Explanation:
The workers which are discouraged can opt out of the labor market since there is no incentive for them work anymore. The workers choosing to go out of the labor market will decrease the overall labor force participation rate. The unemployment rate can also be affected but the main effect would be on labor force participation rate

Answer:
They should operate Mine 1 for 1 hour and Mine 2 for 3 hours to meet the contractual obligations and minimize cost.
Explanation:
The formulation of the linear programming is:
Objective function:

Restrictions:
- High-grade ore: 
- Medium-grade ore: 
- Low-grade ore: 
- No negative hours: 
We start graphing the restrictions in a M1-M2 plane.
In the figure attached, we have the feasible region, where all the restrictions are validated, and the four points of intersection of 2 restrictions.
In one of this four points lies the minimum cost.
Graphically, we can graph the cost function over this feasible region, with different cost levels. When the line cost intersects one of the four points with the lowest level of cost, this is the optimum combination.
(NOTE: it is best to start with a low guessing of the cost and going up until it reaches one point in the feasible region).
The solution is for the point (M1=1, M2=3), with a cost of C=$680.
The cost function graph is attached.
Answer: 88.89 or 89
Explanation: Futures contract refers to a legal binding which obligates a buyer and seller to transact about a commodity, good, security or services at a predetermined price but goods are delivered or paid for in the future.
Given the following ;
Portfolio value(p) = $20million
Portfolio Beta (b) = 1.2
Index price (i) = 1080
Multiplier = 250
Future value(A) = index price × multiplier
Future value(A) = 1080 × 250 = 270000
Number of contracts (N) = (portfolio value × portfolio Beta) ÷ future value
N = ($20,000,000×1.2)÷270000
N = 24000000 ÷×270000
N = 88.8888=88.89
N = 89 (NEAREST whole number)
