C is the correct answer because that's the only answer where all the numbers (i.e. 3, -1, 2) all, when plugged into the function, equal 0. For example:
3³ - (4 × 3²) + 3 + 6 = 0
-1³ - (4 × (-1)²) + (-1) + 6 = 0
2³ - (4 × 2²) + 2 + 6 = 0
As we see, everything adds up to 0. So, C is the correct answer.

Answer:
The percentage of the guests at this hotel called for room service yesterday is 40%
Step-by-step explanation:
We are given
total number of guests called for room services =170
total number of guests did not called for room services =255
