Bridget bought a bag of apples at the grocery store. She gave half of the apples to Ann. Then she gave Cassie 3 apples, keeping 4 apples for herself. How many apples did Bridget buy? 
$\textbf{(A)}\ 3\qquad\textbf{(B)}\ 4\qquad\textbf{(C)}\ 7\qquad\textbf{(D)}\ 11\qquad\textbf{(E)}\ 14$
If we set up an equation, we find out $x=(3+4)\cdot 2$ because 3 apples were left after giving half, then four away. 
We can simplify the equations to $x=7\cdot 2=14.$
The answer is $\text{(E) } 14.$
