Let's use algebra to solve the problem.

Let x be the number of boxes of computer paper sold.

According to the problem, customers bought 5 times as many flash drives as boxes of computer paper. So the number of flash drives sold is 5x.

The total sales on these items is $4200:

6(5x) + 40x = 4200

Simplify and solve for x:

30x + 40x = 4200

70x = 4200

x = 60

Therefore, 60 boxes of computer paper were sold.
