  a. Using multiplication and addition to check the digits, it is invalid because the total is 51 and does not end in a 0

Step-by-step explanation:

The sum of alternate digits is multiplied by 3. Those digits are ...

 0 3 5 0 1 1 . . . . sum of 10

The sum of remaining alternate digits is added to that.

  7 8 2 0 3 1 . . . . sum of 21

The result of the arithmetic ...

  mod(3×10 + 21, 10) = 1 . . . . . should be zero for valid GTIN-12 UPC code
