To calculate the total cost including the tip, we first need to find out how much the tip is and then add it to the original cost of the haircut.
1. **Find the tip amount:**
- Haircut cost: \$13.99
- Tip percentage: 20%
Tip amount = Haircut cost × Tip percentage
Tip amount = \$13.99 × 0.20
Tip amount = \$2.798
2. **Calculate the total cost:**
- Total cost = Haircut cost + Tip amount
Total cost = \$13.99 + \$2.798
Total cost = \$16.788
Rounding to two decimal places, the total cost is approximately **\$16.79**.
