Answer 1

Let's go through each step one by one:

### Step 1: Determine the 20% tip of the food costs.

**Pre-tax food cost**: $105.79
**Tip percentage**: 20%

To calculate the tip:

\[
\text{Tip} = \text{Food Cost} \times \text{Tip Percentage} = 105.79 \times 0.20
\]

\[
\text{Tip} = 105.79 \times 0.20 = 21.158
\]

Rounding to the nearest hundredth:

\[
\text{Tip} = 21.16
\]

### Step 2: Determine the 9% sales tax of the food costs.

**Sales Tax Rate**: 9%

To calculate the sales tax:

\[
\text{Sales Tax} = \text{Food Cost} \times \text{Sales Tax Rate} = 105.79 \times 0.09
\]

\[
\text{Sales Tax} = 105.79 \times 0.09 = 9.4781
\]

Rounding to the nearest hundredth:

\[
\text{Sales Tax} = 9.48
\]

### Step 3: Determine the total price of the meal including the tip and tax.

To find the total price, we sum the food cost, tip, and sales tax:

\[
\text{Total Price} = \text{Food Cost} + \text{Tip} + \text{Sales Tax}
\]

\[
\text{Total Price} = 105.79 + 21.16 + 9.48
\]

Calculating the total:

\[
\text{Total Price} = 136.43
\]

Thus, the final values for each step are:

1. **Tip**: $21.16
2. **Sales Tax**: $9.48
3. **Total Price**: $136.43
