3 nights obvs idk how you couldn't get the answer
The residue in each case is the difference between actual and predicted sales. Thus:
55 - 40 = 15
150 - 150 = 0
325 - 300 = 25
510 - 500 = 10
800 - 780 = 20
1000 - 990 = 10
These add up to be:
15 + 25+ 10 +20 +10
= 80

Answer:

Step-by-step explanation:
So we have the equation:

And we want to find x when y is 9.
So, substitute y for 9 and solve for x:

Multiply:

Add 18 to both sides:

Divide both sides by 2:

So, our answer is 20.5
