That would be a good design for the landscape tablet version but for the
portrait phone version, you will not have enough horizontal space hence
why you're probably better off with a vertical layout for the phone, in
the same way as a cash register receipt:

Pencils:     1.05
               x 5
Paper:    + 10.00
               x 7
Scissors: + 28.79
               x 8
----------------------
Total:       305.57

The fact that you don't get a running total is OK for a version that is
constrained in size. You can show the running total on devices that have
a lot of screen space like a tablet in landscape mode. In practice in
landscape on a tablet, you could actually have the running total as an
additional column on the right.

Now what you would do with 8 pairs of scissors is another question:
Edward Scissorhands Halloween costume?
