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 c(x) = 10x-50. define c(x) and x.

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 .
