Q: Emily bought 9 packs of candy necklaces to give her classmates at school for Valentine’s Day. Each pack had 8 candy necklaces in it. Emily opened one pack at a time. After her classmates took as many as they wanted, there were 40 candy necklaces left. How many packs did Emily open for her classmates?
A: Emily bought 9 packs of candy necklaces * 8 candy necklaces in a pack = 72 candy necklaces. Her classmates took 72 candy necklaces – 40 candy necklaces left = 32 candy necklaces. Since each pack contained 8 necklaces, this means 32 / 8 = 4 packs of candy necklaces were opened. The answer is 4.

[Question]Merill has twice as many marbles as Elliot and the two of them together have five fewer marbles than Selma. If Selma has fifty marbles, how many marbles does Merill have?
[Answer]If Selma has fifty marbles, then Merill and Elliot together have 50 - 5 = 45 marbles. We'll assume the number of marbles that Elliot has is x. If Merill has twice as many marbles as Elliot, then the total number of marbles that Merill and Elliot have together is 2x + x = 45 marbles. This translates to 3x = 45. The number of marbles that Elliot has is x = 45 / 3. This means Elliot has x = 15 marbles. Since Merill has twice as many marbles as Elliot, Merill has 2 * 15 = 30 marbles. The answer is 30.
Q: There are 50 goldfish in the pond. Each goldfish eats 1.5 ounces of food per day. 20% of the goldfish need to eat special food that costs $3 an ounce. How much does it cost to feed these fish?
