Answer 1

multiply the number in each can by the number of cans and add the extras

Explanation:

You can add them all up. This is the total of the number in each can and the extras:

8 +8 +8 +8 +8 +8 +8 +8 +8 +8 +8 +8 +8 +8 +8 +7

Or you can take advantage of the invention of multiplication to simplify repeated addition. Multiply the number in each can by the number of cans, then add the extras.

15×8 +7 = 127
