A sports team sells candles as a fundraiser. The revenue for selling x candles is given by f(x)=12x . The team's profit is $40 less than 80% of the revenue for selling x candles. Write a function g to model the profit. Then find the profit for selling 70 candles.

; The team shall earn $ 632 for selling 70 candles.

Step-by-step explanation:

We notice that statement indicate that every worker gains 80 percent of the revenue for selling candles, which is represented , where is the quantity of sold candles and is measured in US dollars, minus 40 US dollars. Then, the mathematical expression is formed by three components:
