Simon is selling candles for a school fundraiser. For each candle he sells, the school will earn a profit of $2.50.
If c is the number of candles Simon sells and p is the amount of profit his school earns, which is the independent variable and which is the dependent variable? Explain how you determined which variable is the independent and which is the dependent.
Type your answer in the box below.
The independent variable is the number of candles Simon sells (c). This is because the number of candles Simon sells can be chosen or manipulated by Simon himself.
The dependent variable is the amount of profit his school earns (p). This is because the profit earned by the school depends on the number of candles Simon sells. The more candles he sells, the higher the profit will be.
