Answer:

price of B is $27 more than A

Step-by-step explanation:

For brand A;

Using the coordinate (2,24) and (4,48)

Slope m = 48-24/4-2

m = 24/2

m = 12

Get the y-intercept

y = mx+b

24 = 12(2) + b

24 = 24 + b

b = 0

The equation will be;

y = 12x

For cost of 9 bottles of A

y = 12(9)

y = $108

For Brand B:

y = 15x

x is the number of bottles

For cost of 9bottles;

y = 15(9)

y = $135

Hence 9 bottles of brand B cost $135

Take the price difference;

Difference = $135 - $108

Difference = $27

Hence the price of B is $27 more than A
