The percentage increase of the value of Tessa's stock is 22%
Step-by-step explanation:
The percentage of increase = 
× 100%, where:
- New: is the value after increasing
- Old: is the value before increasing
Tessa bought stock in a restaurant for $278.00.
Her stock is now worth $339.16
We need to find the percentage of increase of the value of
Tessa's stock
∵ The initial value of the stock = $278.00
∴ The value of the stock after increasing = $339.16
- Substitute these values in the rule above
∴ The percentage of increasing = 
× 100%
∴ The percentage of increasing = 0.22 × 100%
∴ The percentage of increasing = 22%
The percentage increase of the value of Tessa's stock is 22%

Answer:
Surface Area: 34
Volume: 10
Step-by-step explanation:
Volume = l*w*h
We need to divide the shapes up.
First Shape: 3 length * 1 width * 2 height
Second Shape: 2 length * 1 width * 2 height
6+4=10
Surface Area: 2(lw+wh+hl)
Lets divide the shape into two parts again and plug in the number into the formula.
2(3+2+6) = 2(11) = 22
However, for this, two units are inside to shape because we split it up. We can remove these 2 units.
22-2=20
Now we move to the next shape.
(Keep in mind, you can always just count surface area.)
2(2+2+4) = 2(8) = 16
However, again, two units are inside the shape because this is not just a simple figure.
16-2=14
14+20=34

The average is given by
fav = f(a) - f(b)/a-b
f(-4) = 11
f(6) = 51
fav = 51 -11/-4 -6 = -4
