XYZ$,$ Ltd$.,$ uses $36,000$ units of a product each year. Carrying costs are $$1\mathrm{.}20$ per unit a year, and ordering costs are $$96.$ If XYZ orders $1000$ to $1999$ units, price would be $$2\mathrm{.}25.$ For $2,000$ to $4,999$ units, price would be $$2\mathrm{.}20.$ Price for $5,000$ to $9,999$ units would be $$2\mathrm{.}15.$ For $10,000$ or more units, price would be $$2\mathrm{.}10.$
