A manager must make a decision on shipping. There are two

shippers: A and B$.$ Both offer a two$-$day rate: A for $$540,$ and B for

$$523.$ In addition, A offers a three$-$day rate of $$474$ and a nine$-$day

rate of $$403,$ and B offers a four$-$day rate of $$451$ and a seven$-$day

rate of $$422.$ Annual holding costs are $36$ percent of unit price.

Four hundred and twenty boxes are to be shipped, and each box has a

price of $$150.$ Which shipping alternative would you recommend?
