Best ResponseYou've already chosen the best response.1So we want to subtract the second number by the first because, 1st is the no. of books last week, 2nd is this weeks, we want to work out the difference of the two numbers, this can also be known as subtract \[3\left(\begin{matrix}1 \\ 5\end{matrix}\right)\]  \[1 \left(\begin{matrix}4 \\ 5\end{matrix}\right)\]
