For this case, we have the following generic expression:
[tex]a + b = c\\[/tex]
The commutative property of the addition states that the order of the addends does not alter the sum, therefore the previous expression above can be written as:
[tex]b + a = c\\[/tex]
Thus the expression[tex]8 + 7 = 15[/tex], applying the commutative property, can be written as:
[tex]7 + 8 = 15\\[/tex]
Answer:
Option c
