Question

The function f(x) = 4x + 5,000 represents the amount of money a television is being sold for, where x is the number of televisions being manufactured.
The function g(x) = 20x − 500 represents the cost of production, where x is the number of televisions being manufactured.



What is (f − g)(100)? Explain.

a. $6.9K is the profit made from 100 TVs

b. $3.9K is the profit made from 100 TVs

c. $6.9K is the cost of manufacturing 100 TVs

d. $3.9K is the cost of manufacturing 100 TVs​

Answer 1

Answer:

The opción b

Step-by-step explanation:

the profit is defined by

$Profit=Gain-cost$

In this case $(F-g)(100)=$ is the profit to sell 100 television and is calculated

$F(x)-g(x)=4x+5000-(20x-500)=4x-20x+5000+500=-16x+5500=-16*(100)+5500=3900$

$3900=3.9k$
