"I have $20.00 in the bank and $7.25 in my room，" explained Tom．
"That gives you a total of $27.25．" said Mary，"That is called your capital．The next thing you need to know is how much it will cost you to make each necklace．"
"Well，the pet shop will give me all the feathers the birds lose．I'll have to buy the beads(小珠子) and string，" said Tom．
Mary wrote on the piece of paper：
CAPITAL $27.25
EXPENSES Feathers no cost
String for 10 necklaces $ 2.50
Beads for necklaces + $ 15.00
Total $ 17.50
"How much do you think you can sell such a necklace for?" asked Mary．
"Hmm，" Tom looked thoughtfully and said，"There's a shop in town that sells almost the same kind of necklace for $7.50．if I charge $6.00，people will think that's a bargain．"
"OK，If you sell each necklace for $6.00，you'll make a good profit(利润) on each then，" said Mary．
"Hurry!" Tom cried，"If I sell 20 necklaces，I'll have enough from the profit for the camping trip and $10.00 left over．"
