Well think about it... 12 rolls is already out since they are asking about 16 rolls. 320 divided by 16 is 20. So, the service bought 20 cases of paper towels containing 16 rolls.
(-2x^2 + x + 31) + (3x^2 + 7x -8) = ax^2+bx+c
Simplify the left side of the equation:
-2x^2 + 3x^2 + x + 7x + 31 -8 = x^2+8x+23
Now you'll see that 'a' will have to be 1 (since the coefficient for x^2 is 1)
'b' = 8 (coefficient for x)
'c' = 23 (the constant in the equation)
Add them up!
1+8+23= 32
Hope this helps!
