To calculate the tip for a check total of [tex]$72 at a rate of 20%, you would perform the following steps:
1. Convert the tip rate from a percentage to a decimal to ease the calculation. To convert a percentage into a decimal, you divide it by 100. So, 20% becomes 20 ÷ 100 = 0.20.
2. Multiply the check total by the tip rate (now in decimal form). The formula for calculating the tip is:
Tip = Check Total × Tip Rate
3. Using the numbers provided, the calculation would be:
Tip = $[/tex]72 × 0.20
4. Perform the multiplication:
Tip = [tex]$14.40
Therefore, the correct amount for the tip would be $[/tex]14.40, and the answer to the question is:
a) $14.40
