Plug in instead of P $62.10. Then we get
62.1 = (20 + 0.5x) + 0.15(20+0.5x)
62.1 = 20 + 3 + 0.5x + 0.075x
0.575x = 39.1
x = 68
So, x = 68 pages.

Answer:
x<±1 and x< -3
Step-by-step explanation:
Given the inequality x^2-1/3x+9<0, we are to find the values of x that satisfies the inequality
x^2-1/3x+9<0
x^2-1/3x+9 (3x+9)²<0* (3x+9)²
(x^2-1)(3x+9) < 0
x²-1 < 0 and 3x + 9 <0
x²-1 < 0
x²<1
x<±√1
x<±1
Also 3x + 9 <0
3x < -9
x < -9/3
x < -3
Hence the required values of x are x<±1 and x< -3
