You go to the grocery store to buy dog food. The store has three sizes available:
1. An 8-1b bag for $9.88
2. A 20-Ib bag for $23.44
3. A 40-b bag for $49.00
Which size bag has the lowest cost per pound rounded to the nearest
cent?

B

Step-by-step explanation:

The standard form of equation of a circle is

(x-h)^2+(y-k)^2=r^2

Where h is x coordinate of the centre, k is the y coordinate of the centre and r is the radius of the circle

Hence given that h=5, k=-9 and r=12

So the above equation becomes

(x-5)^2+(y-(-9))^2=(12)^2

(x-5)^2+(y+9)^2=144

Hence the answer is B
