If the price of an item is $2.89 and sales tax is
8%, what is the total cost of the item including
sales tax?

To calculate the total cost of the item including sales tax, follow these steps:

1. **Find the sales tax amount**:
   - Sales tax = (Sales tax rate) × (Item price)
   - Sales tax = 8% × $2.89 = $ \frac{8}{100} \times 2.89 = 0.2312 $

2. **Add the sales tax to the item price**:
   - Total cost = Item price + Sales tax
   - Total cost = $2.89 + $0.2312 = $3.1212

3. **Round the total cost to the nearest cent** (if needed):
   - Total cost ≈ **$3.12**

Thus, the total cost of the item including sales tax is **$3.12**.
