bailey & riley sell magazines.
bailey makes $29 per day plus
$1.50 per magazine she sells.
riley makes $20 per day plus $2
per magazine he sells. one day
riley sold 12 magazines. how
many magazines would bailey
have to sell to make the same
amount of money?

10

Step-by-step explanation:

We can write Bailey's equation as:

29 + 1.50x

and Riley's equation as:

20 + 2x

Where

x is the number of magazines sold

Since Riley sold 12, her total pay for that day would be:

20 + 2x

20 + 2(12)

20 + 24

$44

Now, how many magazines Bailey need to sell? We equate Bailey's equation to 44 and find x:

29 + 1.5x = 44

1.5x = 44 - 29

1.5x = 15

x = 15/1.5

x = 10

hence, Bailey need to sell 10 magazines to make same money as Riley

slope =   (y2 -y1) ÷ (x2 -x1)

slope = (0 -0) / (-5, -7)

slope = 0 / -12 = 0

the slope of the line is zero.   it is perfectly horizontal.
