Mr. J left his entire estate to his wife, his daughter, his son, and the cook. 
His daughter and son got half the estate, sharing in the ratio of $4$ to $3$. 
His wife got twice as much as the son. If the cook received a bequest of $\textdollar{500}$, then the entire estate was: 
$\textbf{(A)}\ \textdollar{3500}\qquad \textbf{(B)}\ \textdollar{5500}\qquad \textbf{(C)}\ \textdollar{6500}\qquad \textbf{(D)}\ \textdollar{7000}\qquad \textbf{(E)}\ \textdollar{7500}$
The wife, daughter, son, and cook received estates in the ratio $6:4:3:1.$ The estate is worth $6+4+3+1 = 14$ units of $$500.,$ which is $\boxed{\textbf{(D)}\ \textdollar{7000}.}$
