Answer:

  40 days

Step-by-step explanation:

Let x represent the original production time. Then 70x is the order quantity involved.

When the same order quantity is produced at a rate of 80 items per day for x-5 days, we have the equation ...

  70x = 80(x -5)

  70x = 80x -400

  0 = 10x -400 . . . . . subtract 70x

  0 = x -40 . . . . . . . . divide by 10

  40 = x . . . . . . . . . . add 40

The original schedule was for production to take 40 days.
