Please help me solve this word problem, please go through logic for how to do it so I can understand it. Thanks!

At a local store, the numbers of gallons of skim milk, 2% milk, and whole milk sold over the weekend are represented by a matrix A.

                               Skim               2%          Whole      

                   Friday        40               64                 52

               Saturday       60               82                 76

                 Sunday        76               96                 84

The selling prices per gallon and the profits per gallon for the three types of milk are represented by B.

                          Selling price        Profit

          Skim                   $3.45       $1.20

              2%                  $3.65       $1.30

         Whole                 $3.85       $1.45

 a) Compute AB and interpret the result.

 b) Find the store's total profit from milk sales for the weekend
