Question

The cost of producing x soccer balls in thousands of dollars is represented by h(x) = 5x + 6. The revenue is represented by k(x) = 9x – 2. Which expression represents the profit, (k – h)(x), of producing soccer balls?

Answer 1

(4x+4)

Explanation:

h(x)=5x+6

k(x)=9x-2

(k-h)(x)= (9x-2-5x+6)

9x-5x=4x -2+6=4

(k-h)(x)= (4x+4)
