So each cd is 15 dollars with a shipping and handling of 5 dollars.
This makes the total amount of money for each cd 20 dollars (15+5).
Now we have to figure out how many cds we can make with 350 dollars.
Number of cds we can make is X.
Cost per cd is 20.
Total money we have is 350 dollars
So 20X=350
We have to get X by itself.
350/20=X
X=17.5
So with 350 dollars we can make and ship 17.5 cds but in the real world it would be 17 cds with 10 dollars left over.
