Answer:
the "they" being referred to is the scientists
Explanation:
Colleges often consider accepting students based on their test scores, as well as certain additional traits. Not all students accepted to college have high SAT scores, however, higher scores increase chances of an academic scholarship. If you are looking for a full academic scholarship, high SAT scores will be beneficial due to the fact that most colleges select students mostly based on test scores. However, you will need additional high grades and test scores in order to be considered for a full scholarship.
(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.
*Step 1 - Simplify 9^2 to 81.
81 + 3^2 + 2^3 + 50 + 32
*Step 2 - Simplify 3^2 to 9.
81 + 9 + 2^3 + 50 + 32
*Step 3 - Simplify 2^3 to 8.
81 + 9 + 8 + 50 + 32
*Step 4 - Simplify 81 + 9 to 90.
90 + 8 + 50 + 32
*Step 5 - Simplify 90 + 8 to 98.
98 + 50 + 32
*Step 6 - Simplify 98 + 50 to 148.
148 + 32
*Step 7 - Simplify
180
Done!
