Q: After Betty gave Stuart 40% of her marble collection, the number of marbles in Stuart's collection increased to 80. If Betty had 60 marbles, how many marbles did Stuart have initially?
A: If Betty had 60 marbles, she gave Stuart 40 / 100 * 60 = 24 marbles. Since the number of marbles in Stuart's collection increased to 80 after Betty gave him 24 marbles, the number of marbles he initially had is 80 - 24 = 56. The answer is 56.
Question: Tiffany attends the carnival and her mother gives her $3 to play on a ring toss game. For every red bucket she tosses a ring into she gets 2 points. For every green bucket she gets three points. She gets zero points for a miss. Every play costs her $1 and she gets 5 rings per play. She's played two games and already gotten 4 red buckets and 5 green buckets. If she plays until her money runs out, what is the most total points she can get for all three games?
Answer: She has 8 points from red buckets because 4 x 2 = 8. She has 15 points from green buckets because 5 x 3 = 15. She has spent $2 on games because 2 x 1 = 2. She has $1 left to spend because 3 - 2 = 1. She can play one more game because 1 / 1 = 1. The best bucket gives three points because 3 > 2. The most she can earn in the final game is 15 because 5 x 3 = 15. The most she can score overall is 38 because 8 + 15 + 15 = 38. The answer is 38.
