Answer 2

The number of candles each girl needs to sell so that the total amount raised is the same for both is

Hailey 70 candles

Kacie 40 candles

Explanation:

Let

x------> the number of candles sold

y----> total amount raised

we know that

Hailey's equation

`y=4x+160` -----> equation A

Please note that Hailey has already raised $160, so he has sold 40 candles.

Kacie's equation

`y=7x+70` -----> equation B

Please note that Kacie has already raised $70, so he has sold 10 candles.

equate equation A and equation B solve for x

`4x+160=7x+70`

`7x-4x=160-70`

`3x=90`

`x=30\ candles`

The number of candles each girl needs to sell so that the total amount raised is the same for both is

Hailey

40+30=70 candles

Kacie

10+30=40 candles
