Enjoy you have lot of money. :-D
Before your family gave you money, you had $10.00 ($7.00 that you had + $3.00 that you had)
Now, you have $150.00 (the $10.00 you had plus $10.00 ($20) plus $30.00 ($50) plus $100.00 ($150)
Now, you have $150.00 (the $10.00 you had plus $10.00 ($20) plus $30.00 ($50) plus $100.00 ($150)
