Answer:

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

Step-by-step 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

The term corresponding angles means that the angles are in the same relative position. if you look at A, r and w are in the same positions if we.were.to overlap the 2 intersections. So they are corresponding angles
