Answer:
(a)
(b)
(c)
Step-by-step explanation:
(a) For the demand equation D(q) we have
<em>P1: 138 Q1: 250</em>
<em>P2: 108 Q2: 1000</em>
We can find <u><em>m</em></u>, which is the slope of the demand equation,
and then we find b, which is the point where the curve intersects the y axis.
We can do it by plugging one point and the slope into the line equation form:
<em>With b: 148 and m: -1/25 we can write our demand equation D(q)</em>
(b) to find the supply equation S(q) we have
<em>P1: 102 Q1: 2200</em>
<em>P2: 102 Q2: 700</em>
<em></em>
Similarly we find <em>m</em>, and <em>b</em>
<em>And we can write our Supply equation S(q):</em>
(c) Now we may find the equilibrium quantity q* and the equilibrium price p* by writing <em>D(q)=S(q)</em>, which means the demand <u><em>equals</em></u> the supply in equilibrium:
We plug 1500 as q into any equation, in this case S(q) and we get:
Which is the equilibrium price p*.
Answer:
405 Problems
Step-by-step explanation:
- One student in class has 15 problems.
- There are 27 students in the class.
Let's <u>multiply</u> 15 by 27.
<em>In all, there would be 405 problems assigned to the whole class.</em>
