Answer:
A and C
Step-by-step explanation:
The cost for 1 cd would be $3.00. To figure this out divide 12 by 4.
We can treat this problem like you regularly subtract fractions. First find the common denominator, which is 15.
So:
5(x+6)/15 = 30/15 + 3(x-2)/15
(5x+6)/15 - (30/15) - (3x - 6)/15
As you already know the answer, I'm assuming you can do the rest.
Hope this helps!
