2(3) + 3(4) + 4(16) + 5(22)
Multiply
6+12+64+110
Add
192
Divide by the total amount of testers
192/((3+4+16+22))
192/45
Divide
About 4.22
Because all the scores are whole numbers, the average score is a 4
I hope this Helps!

Step-by-step explanation:
it is all of the side lengths of the four sides times how many trapezoids there are
Answer:
![Total = \$5d - 2](https://tex.z-dn.net/?f=Total%20%3D%20%5C%245d%20-%202)
Step-by-step explanation:
Represent Alice with A, her friend with F and you with Y.
From the question, we have:
![A = \$d](https://tex.z-dn.net/?f=A%20%3D%20%5C%24d)
--- Twice as much Alice means 2 times Alice's earnings
--- 2 less than her friend
Required
Determine the total amount
![A = \$d](https://tex.z-dn.net/?f=A%20%3D%20%5C%24d)
Substitute
for A in
![F = 2 * \$d](https://tex.z-dn.net/?f=F%20%3D%202%20%2A%20%5C%24d)
![F = \$2d](https://tex.z-dn.net/?f=F%20%3D%20%5C%242d)
Substitute
for F in ![Y = F - 2](https://tex.z-dn.net/?f=Y%20%3D%20F%20-%202)
![Y = \$2d - 2](https://tex.z-dn.net/?f=Y%20%3D%20%5C%242d%20-%202)
The total amount is calculated by adding the earnings of Alice, her friend and you
![Total = A + F + Y](https://tex.z-dn.net/?f=Total%20%3D%20A%20%2B%20F%20%2B%20Y)
![Total = \$d + \$2d + \$2d - 2](https://tex.z-dn.net/?f=Total%20%3D%20%5C%24d%20%2B%20%5C%242d%20%2B%20%5C%242d%20-%202)
![Total = \$5d - 2](https://tex.z-dn.net/?f=Total%20%3D%20%5C%245d%20-%202)
<em>Hence, the total earnings is 5d - 2</em>
the number of people who like both tea and cofee is 50
-10 belongs to integers, rational numbers, and real numbers.
