Maggie took one of her friends out to lunch. the lunches cost $20 and she paid 5% sales tax. if maggie left a 10% tip on the $20, how much in total did she pay

The answer is $20.21

Step-by-step explanation:

So first you find the subtotal cost of the lunches. Each lunch costs $20, so that would be $40 in total.

Now you find the total cost.

She has to pay 5% sales tax so to find the total, you have to multiply 40 by 0.05. That gives you a total of $2. Then you add that to your $40 to get $42.

Now for the tip.

It says to find 10% of 20, so you have to multiply 20 by 0.1. That equals 0.208. Then you add that to 20 to get 20.208.

If you round off, you get a total of $20.21
