Let x = # pairs Gauss Jordans, y = # pairs Roebecks, and z = # pairs K Scottish.

The statement "The team went through a total of 120 pairs" tells us that

The statement that the total cost was $5,700 tells us that

Finally, we are told that "The team went through as many pairs of Gauss Jordans as Roebecks." In other words,

Solving the system of the above three equations in three unknowns gives the solution:

Thus the team used 30 pairs of Gauss Jordans, 30 pairs of Roebecks, and 60 pairs of K Scottish
