Answer:
109 car stereos
Step-by-step explanation:
If 149 car stereos had a CD player (with or without a cassette player), and 40 car stereos had both a CD and a cassette player, the number of stereos with only a CD player is determined by:
![CD_{only} = CD - Both\\CD_{only} =149-40\\CD_{only} =109\ car\ stereos](https://tex.z-dn.net/?f=CD_%7Bonly%7D%20%3D%20CD%20-%20Both%5C%5CCD_%7Bonly%7D%20%3D149-40%5C%5CCD_%7Bonly%7D%20%3D109%5C%20car%5C%20stereos)
109 car stereos had only a CD player.
3 is a rational number because it can be written in the ratio of 3/1 or 6/2.
