Step-by-step explanation:
The mean/average is found by adding all of your values and then dividing by the number of values found.

Find the average of numbers listed
1+4+8

there are 3 numbers listed
13/3=4.33 so the mean is 4.33
Always true .
Negative a is always<0
B<0 so b is negative. Negative times negative is positive > 0 so
-b > -a

So,
775+355.25= $1 130.30
So she made $1 130.30!
