Answer:
the second one it is a function.
Answer:
b. does not form a unique boundary of the feasible solution space.
Step-by-step explanation:
A constraint that does not form a unique boundary of the feasible solution space is called a redundant constraint.
A redundant constraint does not affect the feasible solution region and it commonly occurs in the real world.
By eliminating redundancy, we can simplify the given model.

Answer:
simple interest is $6.8
Miguel pay amount to Julio at the end of 6 months $206.8
Step-by-step explanation:
Given : Miguel Rodriguez borrowed $200 from his brother Julio to pay for books and tuition. He agreed to pay Julio in 6 months with simple annual interest at 6.8%.
To Find : a) How much will the interest amount to?
b) What amount must Miguel pay Julio at the end of 6 months?
Solution :
Formula for simple interest :

Where rate is in decimal
Time is in years
So, rate of interest = 6.8 % = 0.068
Time = 6 months = 
Principal = $200
Thus 

Now To calculate amount must Miguel pay Julio at the end of 6 months
Amount = principal +Simple interest
Amount = 200+6.8 =206.8
Hence the simple interest is $6.8
And Miguel pay amount to Julio at the end of 6 months $206.8
