Answer:
A. -5x = -23
Step-by-step explanation:
First you have to simplify the equation - 4(x - 5) + 8x = 9x - 3
-4x + 20 + 8x = 9x -3
9x - 4x = 20 + 3
5x = 23
=> equivalent to answer A.
The instructor wants the profit to be positive, so
f(n) > 0
70n -400 > 0
n - 400/70 > 0
n > 5 5/7
The instructor must enroll at least 6 students to make a profit.
B. (n + 15) x 3--- That seems to be the correct answer. I hope I helped!
