Let c represent the number of CDs each storage case might hold.

A. c < 5

B. c < 7

C. c < 17

D. C < 20

Answer 1

So total...there are 80 or less cd's....there are 12 randomly on the desk....so 80 - 12 = 68 cd's that should be held by the 4 cases

4c < 68

divide both sides by 4

4c < 68
-------
4 4

c < 17
