Final answer:
Dion left a 20% tip on his $30.00 lunch bill.
Step-by-step explanation:
Dion wants to know what percent of the bill he left as a tip after his lunch. To calculate the tip percentage, we first need to understand that the percentage is a fraction of the total bill represented in terms of 100. The formula to find the percentage is: Tip Percentage = (Tip Amount / Total Bill) x 100. In Dion's case, we'll use the given amounts: $6.00 as the tip and $30.00 as the total bill.
Now we can calculate the tip percentage:
Tip Percentage = ($6.00 / $30.00) x 100
Tip Percentage = 0.20 x 100
Tip Percentage = 20%
Therefore, Dion left a 20% tip on his $30.00 bill.
