Part A: Equation 1: 20x +120
Equation 2: 25x +80
( I think this is the answer)
Part B:
I don’t see a picture attached but I think the answer is 6
87 is the mean.
To find the mean, you must
- add all of the numbers
- divide by the amount of numbers given
In this case, you would want to do (86 + 80 + 95)/3. This would give you an answer of 87.
