Windless surfing company’s marketing manager observes that if the price of designer windsocks is $40, then on average 70 windsocks are sold per month. experience has shown that if the price is raised from $40, then for every $1 increase in price, two fewer windsocks are sold each month.

The answer is x ≤ 50.

Step-by-step explanation:

As, A -70 = -2 (P -40)

A = -2P + 80 + 70

A = -2P + 150

Y = -2x + 150.

When y = 0,

Putting in the values

-2x = -150

x = 75.

-2x + 150 ≥ 50

-2x ≥ -100

x ≤ 50.
