your friend bought 10 CDs and 10 DVDs.. your answer would change if the total cost of the CDs and DVDs were $185 if your friend bought 5 CDs and 5 DVDs.. soo if ur friend bought 5 cds and 5 dvds ur answer would change into 185$ :)

But what equation would be used to find that?

anonymous · Answer

alright..  okay so 1 cd  = 15$ and 1 dvd = 22$  then,
5 cds  = ? and 5dvds = ? 
then multiply 5 with 15 and 22 , you'll get 185
