Answer: Our required equations would be
Step-by-step explanation:
Let the number of candles be 'c'.
In case of Hailey:
Cost of each candle = $4
Amount already raised = $160
So, our equation becomes
In case of Kacie:
Cost of each candle = $7
Amount already raised = $70
So, our equation becomes,
According to question, total amount raised is same for both the cases ,
so, it becomes,
Hence, our required equations would be
