Answer:

Lowest Price - Store B

Middle Price - Store C

Highest Price - Store A

Step-by-step explanation:

Store A Price - $22.50

25 x 0.1 = 2.5

25 - 2.5 = 22.5

Store B Price - $21.60

27 x 0.2 = 5.4

27 - 5.4 = 21.6

Store C Price - $22.1

26 x 0.15 = 3.9

26 - 3.9 = 22.1

KengaRu [80]

I am assuming x is the same thing as b.
−7.5(x−3)=3.75
-7.5x+22.5=3.75
-7.5x=-18.75

At a zoo, the lion pen has a ring-shaped sidewalk around it. The outer edge of the sidewalk is a circle with a radius of 11 m. T

OLEGan [10]

Answer:

$\text{Exact area of the sidewalk}=40 \pi\text{ m}^2$

$\text{Approximate area of the sidewalk}=125.6\text{ m}^2$

Step-by-step explanation:

We have been given that at a zoo, the lion pen has a ring-shaped sidewalk around it. The outer edge of the sidewalk is a circle with a radius of 11 m. The inner edge of the sidewalk is a circle with a radius of 9 m.

To find the area of the side walk we will subtract the area of inner edge of the side walk of lion pen from the area of the outer edge of the lion pen.

$\text{Area of circle}=\pi r^2$ , where r represents radius of the circle.
