Answer:
The smallest number is x = -2
for which this statement holds !!
Step-by-step explanation:
Let as assume the number be x
then the number is one less than twice its reciprocal i.e,

[ For solution refer to the attached file ]
- Method used to solve quadratic equation is Splitting the middle term !!
Summary of information:
total output = 3600 units per year
split into 18 equal orders
cost per order = $40
cost to store a unit for one year = $20
lead time (i.e. storage before shipping) = 5 days
Solution:
quantity split into 18 orders, so 3600/18= 200 units per order.
Order cost = $40 * 18 orders = $720 ..........................(A)
Storage cost:
Each order has 200 units, stored for 5 days = 200*5=1000 unit-days
storage needed for 18 orders = 1000*18 = 18000 unit-days = 50 unit-years
Total storage cost = 50 unit-years * $20 / unit year = $1000...........(B)
Total ordering cost = (A) + (B) = $720+$1000 = $1720
