Colin can read a maximum of 30 pages in one hour. If he has been reading 250 pages for $x$ hours, where $x < 10$ and has $y$ pages left to read, which of the following expresses the relationship between $x$ and $y$ ?

Question

$\begin{array}{1 1} (a)\; 250 - y \leq \frac{30}{x} \\ (b)\; 250 \geq y + \frac{30}{x} \\ (c)\; 250 - y \leq 30x\\ (d)\; 250 + 30 x \leq y \end{array}$
