Kyrian went to the salon and paid $13.99 for a haircut. He left a 20% tip. How much was the total cost? Round to the nearest hundredth. $16.79, $14.27, $15.99, $13.99

20% of $13.99 is (20/100) * $13.99 = $<<20/100*13.99=2.798>>2.798.

So Kyrian paid $13.99 + $2.798 = $<<13.99+2.798=16.788>>16.788.
Rounded to the nearest hundredth, the total cost was $<<16.788=16.79>>16.79. Answer: \boxed{16.79}.
