ANSWER: n = -16
4n + 13n = 17n
19 + 13 = 32
15 - 17 = -2
n = -16
That's a 33% increase.
I calculated this using the formula:
![\frac{|n-o|}{o} * 100](https://tex.z-dn.net/?f=%5Cfrac%7B%7Cn-o%7C%7D%7Bo%7D%20%2A%20100)
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.
