Crayon count

Michelle has five crayons. Victor has fewer of them than Michelle. Wendell has as many as Michelle and Walt have together. All three have seven times more crayons than Victor. How many crayons does Wendell have?

Final Answer:

V =  7

Step-by-step explanation:

$$\begin{gathered} M=5 \\ O<M \\ O=1,2,3,4 \\ V=M+O \\ V+M+O=7\cdot O \\ V+V=7\cdot O \\ V=7\cdot O/2 \\ V+5=6\cdot O \\ V=6\cdot O-5 \\ 7\cdot O/2=6\cdot O-5 \\ 7\cdot O=12\cdot O-10 \\ 10=5\cdot O \\ O=10/5=2 \\ V=6\cdot O-5=6\cdot 2-5=7 \end{gathered}$$
