Answer:
The number of cds to be sold to hit a weekly revenue of 1000 pesos is 25
Step-by-step explanation:
Here, we have the revenue function and we want to know the number of cds to be sold to hit a particular revenue value.
Mathematically from the question;
r = 2x^2 - 10x
in the question; r = 1000
so ;
2x^2 - 10x = 1000
divide through by 2
x^2 -5x = 500
so;
x^2 -5x -500 = 0
x^2 -25x + 20x -500 = 0
x (x -25) + 20(x -25) = 0
(x -25)(x + 20) = 0
x -25 = 0 or x + 20 = 0
x = -20 or 25
Since the number of cds cannot be negative, we only select x = 25 as the correct answer
The answer is the question
