Question: In a grocery store, Julia bought 2 pieces of Snickers and 3 packs of M&M's. If each piece of Snickers costs $1.5 and a pack of M&M's has the same cost as 2 Snickers, how much is Julia's change if she gave the cashier 2 $10 bills?
Answer: Two pieces of snickers cost $1.5 x 2 = $3. One pack of M&M's costs $3 so 3 packs cost $3 x 3 = $9. The total amount that she needs to pay is $3 + $9 = $12. Julia gave the cashier $10 x 2 = $20. So, her change is $20 - $12 = $8. The answer is 8.
[Question]The Giants baseball team is trying to make their league playoff. They have played 20 games and won 12 of them. To make the playoffs, they need to win 2/3 of their games over the season. If there are 10 games left, how many do they have to win to make the playoffs?
[Answer]There are 30 games total because 20 + 10 = 30. They need to win 20 games because 30 x (2 / 3) = 20. The need to win 8 more games because 20 - 12 = 8. The answer is 8.
Q: To win a brand new Bible at Tom Sawyer's Sunday school, a pupil has to win 10 yellow tickets; each yellow ticket is obtained by trading in 10 red tickets; each red ticket is obtained by trading in 10 blue tickets; and blue tickets are earned by memorizing two Bible verses. But rather than go to all that trouble, Tom Sawyer has traded various toys and treasures of his with his friends until he has gathered 8 yellow, 3 red, and 7 blue tickets. How many more blue tickets would he need to earn to win a new Bible?
A: A red ticket is equal to 10 blue tickets, and a yellow is equal to ten red tickets, so a yellow ticket is also equal to 10 * 10 = 100 blue tickets. It takes 10 yellow tickets to win a Bible, or 10 * 100 = 1000 blue tickets. Tom has 8 yellow tickets, which are worth 8 * 100 = 800 blue tickets. He also has 3 red tickets, which are worth 3 * 10 = 30 blue tickets. Added with his 7 blue tickets, he has 800 + 30 + 7 = 837 blue tickets' worth of tickets. So he still needs to earn 1000 - 837 = 163 blue tickets. The answer is 163.
