Question

If cost Rs x each to make the first thousand copies of a compact disc and Rs y to make each subsequent copy. If z is greater than 1000, how much will it cost to make z copies of the
compact disc?​

Answer 1

Answer:

1000(x-y)+yz

Step-by-step explanation:

Total copies to be made =z

Cost of first 1000 copies =1000x

Now remaing copies has to be made =z−1000

Cost of remaining copies =y×(z−1000)

Total cost =1000x+y×(z−1000)

=1000(x−y)+yz
