To calculate a tip:
1. Identify the total bill amount. In our case, let's assume the bill total is [tex]$100.
2. Determine the tip percentage. For example, let’s use 15% as the tip percentage.
3. Convert the tip percentage to a decimal. This means dividing the tip percentage by 100. So, 15% as a decimal becomes 0.15.
4. Multiply the bill total by the tip percentage (converted to a decimal). This step gives the tip amount. Thus:
$[/tex][tex]$
\text{Tip Amount} = \text{Bill Total} \times \left(\frac{\text{Tip Percentage}}{100}\right)
$[/tex][tex]$
which simplifies to:
$[/tex][tex]$
\text{Tip Amount} = 100 \times 0.15 = 15.0
$[/tex]$
From the given steps, you can see that the correct option is:
c. Multiply the bill total by the tip percentage (converted to a decimal).
