The correct answer is $44.20. 
If we add up all the tips, the total is $442. If we divide this by the number of days (10), then we find the mean.
442 / 10 = 44.2
        
             
        
        
        
Answer:
x = - 7
Step-by-step explanation:
Given
- 5(x - 2) - (x + 2) = 50 ← distribute parenthesis on left side
- 5x + 10 - x - 2 = 50, that is
- 6x + 8 = 50 ( subtract 8 from both sides )
- 6x = 42 ( divide both sides by - 6 )
x = - 7
