Answer:
C
Step-by-step explanation:
A, B, and D equal -4, while C equals 4.
A positive number times/divided by a negative number (or vice versa) is a negative number. A negative number times/divided by a negative number (or vice versa) is a positive number.
Profit = Revenue - Cost = R(x) - C(x) = (x^2 + 20x + 50) - (50x + 30) = x^2 - 30x + 20
