Answer:
B.
Step-by-step explanation:
The easiest way is to substitute 8 for x in the first equation,
That's a 33% increase.
I calculated this using the formula:

Where n = the new value (16 in your question), o = the old value (12 in your question) and the result is outputted as a percent increase. You can check that this is correct by finding 33% of 12, adding the result to 12, and checking that the result equals your "new" number.
Note that 33% is only an approximation as your question requires a number rounded to the nearest whole.
The answer would be 32. take your 26 and add 18 then subtract 12. then rework it forward if you don't understand.
