Answer:
c(x) is the revenue function
x is the number of candles
Step-by-step explanation:
Given : Andrea is selling candles as a fundraiser. She spent $50 on supplies for the making of 85 candles, which she plans to sell for $10 each. The function of her revenue can be modeled by [tex]c(x) = 10x-50[/tex].
To find : Define c(x) and x ?
Solution :
The function of her revenue can be modeled by [tex]c(x) = 10x-50[/tex].
Here, c(x) is the revenue function
Revenue is the total amount earned by firm.
R(x)=(price per unit) (number of units produced or sold)
and x is the number of candles.
According to question,
We have given x=85,
The revenue of 85 candles is given by,
[tex]c(85) = 10(85)-50[/tex]
[tex]c(85) =850-50=800[/tex]
The revenue of 85 candles is $800.
