If there are 10 reams, and each ream is 32 ounces, then there is 320 ounces total im the case! Then, if you know that there are 16 ounces in a pound, then you can do 320/16, and get a total of 20 pounds in the case!
Hope this helped!
We will have the following:


So, the solution would be:
Equation of circle
(x-h)^2 + (y-k)^2 = r^2
=> (x-10)^2 + (y+4)^2 = 4 is the answer
Y=2/3x+2/3 bc slope is 2/3 and 4-2/4-1=2/3
The correct solution is 75.
