To calculate the total amount Mr. Chin pays, including the tip, we first need to find out how much the tip is based on the hotel bill of $143.
First, calculate the tip:
\[ \text{Tip} = 12% \times 143 = 0.12 \times 143 = 17.16 \]
Now, add the tip to the hotel bill:
\[ \text{Total Amount} = \text{Hotel Bill} + \text{Tip} = 143 + 17.16 = 160.16 \]
Therefore, the total amount Mr. Chin pays, including tip, is $160.16.
