A standard tip for a waiter or waitress is between 15% and 20% of the bill. If Sue wants to tip 20% of her $45.00 dinner bill, how much should she leave the waiter as a tip?

Just turn you percent into a decimal (move the decimal point 2 places to left) and multiply the two numbers together.

To calculate the amount Sue should leave as a tip, you can follow these steps:

Step 1: Determine the percentage of the bill she wants to tip. In this case, she wants to tip 20% of her $45.00 dinner bill.

Step 2: Calculate the tip amount by multiplying the bill amount by the tip percentage. So, multiplying $45.00 by 20% (or 0.20) gives us:

$45.00 x 0.20 = $9.00

Therefore, Sue should leave a $9.00 tip for the waiter.
