Using SAS programming:

The three variables and their types are shown below: Customer$\_$id $$,$ Order$\_$month, and Sale$\_$amt

$1)$ Write a macro with the $\%$LET statement to find the sales amounts when the month$=1($of the Order$\_$month variable$)$ and make sure it has a title that references the macro you wrote in terms of the month selected $($something like $$Orders for $...).$

$2)$ Next, write another macro that uses $\%$MACRO and $\%$MEND to create a program that will use a PROC PRINT to print the sales amounts $($so the var statement will be Sale$\_$Amt$)$ and a PROC MEANS to generate the mean Sale$\_$Amt
