Shinya went to the salon The cost of her haircut was $16.00 He tipped the barber 15% what was the total cost
The total cost of the haircut was $16.00.
To calculate the tip, we need to find 15% of $16.00.
15% of $16.00 = (15/100) * $16.00 = $2.40
Therefore, the total cost including the tip is $16.00 + $2.40 = $18.40.
