Step-by-step explanation:
I'm not sure how many pizzas were ordered, but let's say you just got one large pizza that was $18.
First, the sales tax - 6%
$18 + 6% = $19.08
Then you give a 15% tip.
$19.08 + 15% = $21.94

Answer:
Davide's age is 10.
L'età di Davide è 10.
Step-by-step explanation:
The average age of Aldo, Bruno, Carlo and Davide is 16 years.
I am going to say that:
x is Aldo's age.
y is Bruno's age.
z is Carlo's age.
w is Davide's age.
Average of the 4 is 16 years.
This means that:
![16 = \frac{x + y + z + w}{4}](https://tex.z-dn.net/?f=16%20%3D%20%5Cfrac%7Bx%20%2B%20y%20%2B%20z%20%2B%20w%7D%7B4%7D)
![x + y + z + w = 64](https://tex.z-dn.net/?f=x%20%2B%20y%20%2B%20z%20%2B%20w%20%3D%2064)
If we do not consider Davide, the mean is 18. So
![18 = \frac{x + y + z}{3}](https://tex.z-dn.net/?f=18%20%3D%20%5Cfrac%7Bx%20%2B%20y%20%2B%20z%7D%7B3%7D)
![x + y + z = 54](https://tex.z-dn.net/?f=x%20%2B%20y%20%2B%20z%20%3D%2054)
Replacing in the first equation:
![x + y + z + w = 64](https://tex.z-dn.net/?f=x%20%2B%20y%20%2B%20z%20%2B%20w%20%3D%2064)
![54 + w = 64](https://tex.z-dn.net/?f=54%20%2B%20w%20%3D%2064)
![w = 10](https://tex.z-dn.net/?f=w%20%3D%2010)
Davide's age is 10.
L'età di Davide è 10.
