Five girls are collecting shells on a beach. They are putting them in buckets that each hold 24 shells. At the end of the collecting time, they are going to ensure that they all have the same number of shells. Four of them are only two short of filling their bucket, but the youngest one is lagging behind with her total. Each of the others give her three shells from their buckets in order to equalize the numbers collected.How many shells did the youngest girl collect for herself?
Each of the four must have 22 shells in their baskets before giving any away
After giving the yougest one 3 shells....they each have 19
Let x be the number of shells the nuumber of shells she had in her basket before being given 3 shells by each of the other four
Number she started with + 4 (3) = 19
Number she started with + 12 = 19 subtract 12 from both sides
Number she started with = 7
