Julie the jeweler has fifteen gold necklaces worth $120 each, nine silver necklaces valued at $90 each, ten plated necklaces valued at $60 each and thirty beaded necklaces worth $15 each. what is the average value of a necklace at julie’s shop?

1. Multiply each amount of money by the number of jewelry. :120x15=1800   90x9=810   60x10=600   15x3=45.
2. Add all the amounts of jewelry together. : 15+9+10+30=64
3. Add all the answers in step 1 together. :1800+810+600+45=3255
4. Divide your answer in step 3 by the answer in step 2: 3255/64=50.859375
5. 51.0 is your answer if you round it up!!
I know this is correct! I worked this myself twice!!
Hope this helps!!:)
