The total cost of collating 1,000,000 per month is:
The total cost of collating 2,000,000 per month is:
The monthly volume at which the automatic process is preferred is 1,538,462.
When collating 1,000,000, the cost is:
= 1,000,000 / 5,000 x $10 per hour
= $2,000
When collating 2,000,000, cost is:
= 2,000,000 / 5,000 x 10
= $4,000
When collating 1,000,000, the cost is:
= (1,000,000 / 1,000 x 0.05 per thousand units ) + 3,000 operating cost
= $3,050
When collating 2,000,000, cost is:
= (2,000,000 / 1,000 x 0.05 per thousand units ) + 3,000 operating cost
= $3,100
Assume the volume is x:
(x / 1,000 x 0.05 per thousand units ) + 3,000 operating cost = x / 5,000 x 10
0.00005x + 3,000 = 0.002x
0.00195x = 3,000
x = 3,000 / 0.00195
= 1,538,462 photocopies
