Answer:

$26.14

Step-by-step explanation:

You want to tip the waiter 20% of your bill. First, we need to find 20% of $21.78 and then add it to the bill.

20% = 20/100 = 0.2

Now we multiply 0.2 with 21.78 to find tip amount. Shown below:

0.2 * 21.78 = $4.36

We now have to add it to original price:

$21.78 + $4.36 = $26.14

The cost of lunch bill (with tip) is $26.14

Answer: $26.14

Explanation: If the tip is 20%, we have to find 20% of $21.78.

20% of 21.78 is 4.356.

We now add this number to your bill.

21.78 + 4.356 = 26.136

Now we round up 26.136, which is 26.14.
