Chris, Ian and Lovejoy found a collection of 72 golden oldies in a flea market. The price for the whole collection was $9.00. Chris chipped in $2, Ian $3, and Lovejoy $4 to buy them all. If they decided to split up the collection, how many records should each of them keep?
Chris contributed 2/9 of the cost, Ian 3/9 of the cost, and Lovejoy 4/9 of the cost. So Chris should get (2/9) x 72 = 16 of the records, Ian should get 24 records, and Lovejoy should get 32. Check: 16 + 24 + 32 = 72.
