Answer: Equilibrium price would be $13.33 and equilibrium quantity would be 133.3 units.

Step-by-step explanation:

Since we have given that

Demand function is stated as

$D(p)=200-5p$

Supply function is stated as

$S(p)=10p$

We need to find the equilibrium price and quantity for this device.

For equilibrium, D(p) = S(p).

so, it becomes,

$200-5p=10p\\\\200=10p+5p\\\\200=15p\\\\p=\dfrac{200}{15}\\\\p=\$13.33$

and when we put the value of p in any function:

$Q=10\times 13.33=133.3\ units$

Hence, Equilibrium price would be $13.33 and equilibrium quantity would be 133.3 units.

Whats the answer to 45=x(14-x)

ElenaW [278]

$45=x(14-x)\\ \\45=14x-x^2\\ \\x^2-14x+45=0\\ \\\Delta = b^{2}-4ac = (-14)^{2}-4*1* 45=196-180=16 \\ \\x_{1}=\frac{-b-\sqrt{\Delta }}{2a} =\frac{14- \sqrt{16}}{2}=\frac{14-4}{2}= \frac{12}{2}=6\\ \\x_{2}=\frac{-b+\sqrt{\Delta }}{2a} =\frac{14+\sqrt{16}}{2}=\frac{14+4}{2}= \frac{18}{2}=9$
