Answer:

14

Explanation:

6 - 1.50 = 4.5

63 / 4.5 = 14

We have the following equality


6x=1.5x+63

where x is the number of lanyards, solving for x


\begin{gathered} 6x-1.5x=63 \\ 4.5x=63 \\ x=(63)/(4.5) \\ x=14 \end{gathered}

Therefore you must sell at least 14 cords to have equal revenue and expenses
