Computers The CTN Corporation has a supply of 3600 computer

Computers - The CTN Corporation has a supply of 3600 computers. It wishes to ship 128 computers each week until its supply drops to 2000. How long will this take?

Solution

let the supply be y

Initially there are 3600

It ships 128 computers each week . Let the number of weeks be represented by x

The algebraic expression is y = -128x + 3600

Negative since the supply is dropping

Now the supply drops to 2000

==> 2000 = -128x + 3600

==> 128x = 1600

==> x = 1600/128

==> x = 12.5

Hence it approximately takes 13 weeks for the supply to drop to 2000 units.
