Well, you can't really determine the price of 1 book, but you can find out the average cost.

280 - 16 = 8x (x = cost of 1 book)
264 = 8x
264/8 = 8x/8
33 = x

So the average cost of one book is 33$( A little expensive if I do say so myself)
Hope this helped!

Beatrice is using a cylinder shape container to hold 52 in³ of liquid. The height of the container is 4 inches tall. What is the
asambeis [7]

Cylinder Volume = PI * radius ^2 * height

52 = PI * radius ^2 * 4

radius ^2 = 52 / (PI * 4)

radius ^2 = 52 / 12.5663706144

radius ^ 2 = 4.1380285204

radius = 2.0342144726


OR a good approximation of the radius is 2 inches
