EBI Solar uses a high$-$tech process to turn silicon wafers into tiny solar panels. These efficient and inexpensive panels

are used to power low$-$energy hand$-$held electronic devices. Last year, EBI Solar turned their inventory $4\mathrm{.}5$ times and

had a cost of goods sold of $$2\mathrm{.}5$ million. Assume $52$ business weeks per year.
