Ted bought seven cds. a week later half of all his cds were destroyed in a fire. there are now only 20 cds left. with how many did he start?

33 CDs

Since half the CDs were destroyed, you need to find the total CDs Ted had before the fire.

20 CDs = 1/2 of what Ted had

20*2=40 CDs

Now, subtract 7 from the 40 CDs to find the amount he had in the beginning.

40-7=33

33CDs

20 is half. 40 he had after buying 7. 40-7 is 33.
