Sally’s dinner bill came out to be $30 and she wants to leave a 20% tip how much is her total bill? Tax is included in the $30
First, calculate the amount of the tip by multiplying the bill total by the tip percentage: $30 * 0.20 = $<<30*0.20=6>>6.
Then, add the amount of the tip to the bill total to find the total bill: $30 + $6 = $<<30+6=36>>36. Answer: \boxed{36}.
To find out the total bill, we need to calculate the tip amount first. The tip amount is 20% of the dinner bill.
Step 1: Calculate the tip amount:
Tip Amount = 20% of $30
= (20/100) * $30
= 0.2 * $30
= $6
Step 2: Add the tip amount to the dinner bill:
Total Bill = Dinner Bill + Tip Amount
= $30 + $6
= $36
Therefore, Sally's total bill, including the 20% tip, is $36.
