Step-by-step explanation:
Since we have given that
Demand function is given by

Supply function is given by

According to question, we need to find the price for which the supply equals the demand, i.e. Equilibrium price and quantity.

So, at $21.85, the supply will equal to demand.
Answer:
The amount $15000 is divided as
in 2% = $7000
in 5% = $8000
Step-by-step explanation:
It is given that the total amount is $15000 and rates of interests are 2% and 5%.
<em>Let the amount invested in 2% be "x", so the amount invested in 5% is (15000 - x).</em>
The annual interest on x part is given as,
= 
Similarly, The annual interest on (15000 - x) part is given as,
= 
the total annual interest is given as $540
Thus, <em>540 =
</em>
<em>54000 =
</em>
<em>21000 = 3(x)</em>
x =
= 7000
Thus the shares are $7000 and (15000 - 7000) $8000 .
