Question

Lee sells electronics. He earns a 5% commission on each sale he makes. If Lee wants to make $100 in commission, what is the dollar amount of electronics he must sell?

Answer 1

This questions can be answer by the rule of three.

`\begin{gathered} 100\rightarrow5 \\ x\rightarrow100 \end{gathered}`

Then he has to sell

`\begin{gathered} x=(100\cdot100)/(5) \\ =(10000)/(5) \\ =2000 \end{gathered}`

Therefore, Lee has to sell $2000 of electronics.
