[Question]Harry's birthday was three weeks after the closing of the school. His three friends decided to contribute an equal amount of money to throw him a party. Harry added $30 to the contribution, making the total contribution three times as much as Harry contributed. Calculate the total amount of money that each of Harry's friends contributed.
[Answer]If the total contribution was three times as much as Harry contributed, and Harry contributed $30, the total contribution was 3 * $30 = $90. Since Harry contributed $30, his three friends together contributed $90 - $30 = $60. Since the three friends were contributing an equal amount, each friend contributed $60 / 3 = $20. The answer is 20.

[Question]Zayne sells bracelets for $5 each and two for $8. If he started with 30 bracelets and made $60 from selling bracelets for $5 each, how much in total did he make from selling his bracelets?
[Answer]If the bracelets he sold at $5 made $60, he sold $60 / $5 = 12 bracelets. If the total number of $5 bracelets was 12, then the total number of bracelets he sold was 30 - 12 = 18. If he was selling a pair of bracelets at $8, he sold 18 / 2 = 9 pairs. The total amount of money he made from selling the nine pairs is $8 * 9 = $72. His total earnings from selling all of his bracelets are $72 + $60 = $132. The answer is 132.

First find the total number of stars she saw in the west: 120 stars * 6 = 720 stars. Then add the number she saw in the east to find the total number: 720 stars + 120 stars = 840 stars. The answer is 840.
