Chapter 5.1, Problem 11E

In Exercises 1-14, $D\left(x\right)$ is the price, in dollars per unit, that consumers will pay for x units of an item, $S\left(x\right)$ is the price, in dollars per unit, that producers will accept for x units. Find (a) the equilibrium point, (b) the consumer surplus at the equilibrium point, and (c) the producer surplus at the equilibrium point.

$D\left(x\right)=\frac{1800}{\sqrt{x+1}},S\left(x\right)=2\sqrt{x+1}$

a. (a) $\left(899,\$60\right)$

b. (b) $50,460

c. (c) $17,941.33
