(A) The supply function generally is considered to have positive slope. Qa has positive slope. Qb has negative slope, so is probably the demand function.
supply function: Qa
demand function: Qb
(B) The equilibrium price is the price that makes supply equal to demand.
Qa = Qb
50 +p = 200 -4p
5p = 150
p = 30
The equilibrium price is 30.
(C) The price elasticity of supply is computed as
Es = (dQa/dp)·(P/Qa) = 1·p/(50+p)
Es = p/(50+p)
At p=30, the numerical value is Es = 30/80 = 3/8. Qualitatively, the supply is inelastic.
If I were a forensic scientist and asked to identify drugs at a crime scene, you would take samples where residue is likely to be present.
<h3>What is a crime scene?</h3>
A crime scene is a term used to refer to the location where a crime occurs and the arrangement of evidence to determine how events related to the crime occurred at that location.
<h3>What is a sample?</h3>
A sample is a tool used in forensic investigation to determine the existence of an element or substance at a crime scene.
For example, in this case we can take samples from the corpse's hands, nose and mouth to determine if he used drugs prior to his death.

Answer:
Washington was nervous about the school succeeding.
Explanation:
From the excerpt, the detail about the early days of a Tuskegee normal school that appears only in this autobiography is "Washington was nervous about the school succeeding."
This is evident when Washington stated that about three months after the school was opened they were having the GREATEST ANXIETY about their work. This implies that Washington and other staff were NERVOUS about the success of the school.
Option C "the original school burned down after it was opened" is not correct and there was nothing like that in that excerpt.
Option D "Washington wanted students to build the new school" is not correct either.
Option B " The school was moved to the site of an old plantation" was closer but not correct either. This is because it is not stated whether the school was eventually moved to the location. It was only stated that the location is what they wanted
