Question

What does the independent variable represent in this situation? A The number of scents B The number of candles Sallie sells C The cost of each candle Sallie sells D The total amount of money Sallie earns selling candles

Answer 1

B The number of candles Sallie sells

Explanation:

Given the equation :

y = 8x

y = amount earned ; x = number of candles sold

Cost per candle = 8

The Independent variable is the number of candles sallie sells as it is this variable which determines the amount which sallie will earn from candle sales (dependent variable). In essence, the variable which determines or affects the dependent variable is the independent variable.
