A company purchases a copier for $2000. The material for each order costs $15. Estimate how many orders must be printed for the average cost per order to fall $65.

Answer 1

Let number of order be x

Cost of copier + cost of material for x orders = 2000+15x

Average cost = 2000 +15x

----------------

x

so (2000 + 15x)/x = 65

2000 = 65x - 15x

x =2000/50 = 40
