Solve the problem.
-The U.S. Maritime Administration estimated that the cost per ton of building an oil tanker could be represented by the model $y = \frac { 112,000 } { x + 225 }$, where $y$ is the cost in dollars per ton and $x$ is the tons (in thousands). What size of oil tanker (in thousands of tons) can be built for $\$ 200$ per ton?
A) 335 thousand tons
B) 264 thousand tons
C) 785 thousand tons
D) 34 thousand tons

To find the size of the oil tanker that can be built for $200 per ton, substitute $y = 200$ into the given model and solve for $x$: $200 = \frac{112,000}{x + 225}$. Solving this equation for $x$ gives $x = 335$ thousand tons.
