Answer:
- it would cost $17.5 for 5 bacon egg and cheese
- it would cost $28 for 8 bacon egg and cheese
To find unit rate:
take two best coordinates: (2,7),(4,14)
then find unit rate using: [tex]\boxed{\frac{y2-y1}{x2-x1} }[/tex]
using the formula:
[tex]\frac{14-7}{4-2}[/tex]
[tex]\frac{7}{2}[/tex]
[tex]3.5[/tex] ...........this is unit rate.
Using y = mx + b..............Here the y-intercept is 0 and slope(m) is 3.5
y = 3.5x + 0
y = 3.5x
Now using this find bacon prices:
(a)
y = 3.5x
y = 3.5(5)
y = 17.5
(b)
y = 3.5x
y = 3.5(8)
y = 28
