Develop a lot$-$for$-$lot solution and calculate total relevant costs for the gross requirements in the following table$*.$

$\backslash$table$[[$Period$,1,2,3,4,5,6,7,8,9,10,11,12],[$Gross requirements,$30,,40,,30,60,20,,10,70,,60]]$

$*$Holding cost $=$$$\frac{3\mathrm{.}50}{?}$ unit$/$week; setup cost $=$$$200$; lead time $=1$ week; beginning inventory $=40.$
