Pam runs a mail$-$order business for gym equipment. Annual demand for Tricoflexers is $18,000.$ The annual holding cost per unit is $\backslash (\backslash$$ $4\mathrm{.}00\backslash ),$ and the cost to place an order is $\backslash (\backslash$$ $33\backslash ).$ a$.$ What is the economic order quantity? The EOQ is $($Enter your response rounded to the nearest whole number.$)$ b$.$ Suppose demand for TricoFlexers doubles, to $36,000.$ The EOQ for the new value of demand is $($Enter your response rounded to the nearest whole number.$)$ Does the EOQ also double? A$.$ No$,$ the EOQ does not double as the annual demand doubles. The EOQ is inversely proportional to the demand. B$.$ No$,$ the EOQ does not double as the annual demand doubles. The EOQ increases by the square$-$root of the product of two$-$times theThe EOQ for the new value of demand is $($Enter your response rounded to the nearest whole number.$)$ Does the EOQ also double? A$.$ No$,$ the EOQ does not double as the annual demand doubles. The EOQ is inversely proportional to the demand. B$.$ No$,$ the EOQ does not double as the annual demand doubles. The EOQ increases by the square$-$root of the product of two$-$limes the demand times ordering cost, divided by holding cost. C$.$ Yes, the EOQ doubles because the EOQ is directly proportional to the demand. D$.$ No$,$ the EOQ does not double as the annual demand doubles. The EOQ is inversely proportional to the square$-$root of the demand. c$.$ The manufacturer of TricoFlexers has agreed to offer Pam a price discount of $\backslash (\backslash$$ $9\backslash )$ per unit $(\backslash$$$24$ rather than $\backslash (\backslash$$ $33\backslash ))$ if she buys $1,800.$ Assuming that annual demand is still $18,000,$ how many units should Pam order at a time? Pam should order units at a time. $($Enter your response rounded to the nearest whole number.$)$
