A is the answer because remember A is for adults and C is for Children.
To solve for j, the first step is to get rid of the -5 by adding it to both sides to get:
8j+j=72
Then, add like things, which would be 8j and j (aka 1j) to get:
9j=72
Finally, divide both sides by 9 to get the answer, which is:
j=8
