The number of wrenches that can be produced at a given price can be predicted by the formula $s = \sqrt { 65 x }$ , where $s$ is the supply (in thousands)and $X$ is the price (in dollars). If the demand $d$ for the wrenches can be predicted by the formula $d = \sqrt { 324 - 4 x ^ { 2 } }$ , find the equilibrium price.
A)$6
B)$5
