Answer: b) write an equation that you can use to get the amount of the tip. t= __ ($__)

Explanation: You want to leave a 20% tip on a meal that cost $45.

First, convert the 20% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 20%) by 100%.So, the conversational term "20%" becomes 20% / 100% = 0.20 in terms of a real mathematical number.

Second, you need to find out what 20% of your $45 meal cost is.This is always done by multiplying 0.20 by $45.00, or

0.20 x $45.00=$9.00.

So, the amount of tip you are going to leave is $9.00.

This makes the total cost of your meal (to write on your charge)

$45.00 + $9.00 = $54.00.

I hope this helps <3
