Answer 2

Answer: A) $4c+7c=160+170$

Step-by-step explanation:

Let c represents the number of candies sold.

Given : Hailey is selling candles for $4 each and has already raised $160.

i.e. $4c=160$    (1)

Kacie is selling candles for $7 each and has already raised $70.

i.e. $7c=70$    (2)

Total amount raised is given by :-

$4c+7c=160+170$   Add (1) and (2)

Hence, the equation can be used to find c, the number of candles each girl needs to sell so that the total amount raised is the same for both Hailey and Kacie will be $4c+7c=160+170$
