Question

You have a rack that can hold 30 CDs. You can fit 7 more CDs on the rack before the rack it full. How many CDs are in the rack?

Answer 1

23 CDs

Explanation:

This equation represents the situation:

x+7=30

where x is the number of CDs on the rack

Now we just solve for x to figure out how many CDs there are.

x+7=30

x=23

just subtract 30-7=23

Answer 2

The answer would be 23 because 30 minus 7
