75 thousand

Step-by-step explanation:

R = - x³ + 102x² + 1575x

To maximize R, find dR/dx and set to 0:

dR/dx = - 3x² + 204x + 1575

0 = - 3x² + 204x + 1575

0 = x² - 68x - 525

0 = (x + 7) (x - 75)

x = - 7 or 75

Since x can't be negative, x = 75.

Therefore, the revenue is a maximum when 75 thousand units are produced.
