To find the tip amount for Delilah and her friends' bill, we first need to understand what the percent values mean and how to apply them correctly.
1. Identify the Total Bill: The total bill amount is $140.
2. Determine the Tip Percentage: The group wants to give a tip of 25% of the total bill.
3. Calculate the Tip Amount:
- We start by converting the percentage to a decimal. This is done by dividing 25 by 100, which gives us 0.25.
- Next, we multiply the total bill ($140) by the decimal equivalent of the tip percentage (0.25) to find the tip amount.
[tex]\[ \text{Tip Amount} = \[tex]$140 \times 0.25 = \$[/tex]35.0 \][/tex]
Therefore, the amount of the tip is \$35.0.
