Stacy buys 3 cbs in a set for29.98. she saved $6.44 by buying the set instead of buying the individual cds. if each cd costs the same amount, how much does each of the 3 cds cost when purchased individually? plz me

Add $29.98 and $6.44 together and divide by 3. The answer is $12.14 each CD when purchased individually.

First you have to find the number in between 44 and 55. 
First you subtract 55-44=11 then divide 11/2= 5.5 now just ad 44+5.5 and get 49.5.
Now that you have the middle number since there are two people painting the room you have to divide 49.5 by 2 and get 24.75
Final Answer 24.75 Hours
