When x represents whole numbers less than 200, the function f (x) = 2x - 20 represents the profit earned from selling x carnations for a school fund-raiser. What is the value of f (140) ?

260

Step-by-step explanation:

When x represents whole numbers less than 200, the function

f (x) = 2x - 20 ... (1)

represents the profit earned from selling x carnations for a school fund-raiser.

Therefore, the profit earned from selling 140 carnations for the school fund-raiser will be given by the equation (1) as

f (140) = 2 (140) - 20 = 280 - 20 = 260.

Therefore, 260 is the value of f (140). (Answer)
