Question: Mary bought six apples from the store. From the apples she bought, for each that Mary ate, she planted two trees from the remaining ones. How many apples did Mary eat?
Answer: She planted eight trees. This means she used half of that amount of apples, which is 8 trees / 2 trees / apple = 4 apples. That means that she planted four of the six apples she bought, leaving only 6 apples - 4 apples = 2 apples to be eaten. The answer is 2.
[Question]A soccer team had 24 players prepared for a soccer game. The first half saw 11 players start the game with 2 substitutions made. In the second half, the team made twice as many substitutions as it made in the first half. How many players on the team did not play that day?
[Answer]With two substitutions, 11 + 2 = 13 players from the team played the game in the first half. In the second half, the team made twice the number of substitutions it made in the first half, a total of 2 * 2 = 4 substitutions. The total number of players who played the game is 13 + 4 = 17. If the soccer team had 24 players prepared for the soccer game, the number of players who did not play the game is 24 - 17 = 7 players. The answer is 7.
Q: Daniela goes shopping during a sale. She finds out that the store has 40 percent off on shoes and 20 percent off dresses. If Daniela buys 2 pairs of shoes originally priced at $50 a pair and a dress originally priced at $100, how much money does she spend?
A: Two pairs of shoes at $50 a pair costs $50 x 2 = $100. The shoes are discounted by 40 percent so she only pays 100 - 40 = 60 percent of the original price. Therefore the two pairs of shoes cost $100 x 0.60 = $60. The dress is discounted by 20 percent so she only pays 100 - 20 = 80 percent of the original price. Therefore the dress costs $100 x 0.80 = $80. In total Daniela spends $60 + $80 = $140 for two pairs of shoes and a dress. The answer is 140.
Question: Amy's grandfather gave her $100 for her birthday. Amy bought 3 dolls, each of which cost $1. How much money does Amy have left?

[Question]Ali, Nada, and John have a total of $67 in their wallets. Ali has $5 less than Nada and John has 4 times more than Nada. How much money does John have?
[Answer]Let's say that N is what Nada has, J is what John has, and A is what Ali has. We know that A = N - 5 and J = 4N. We also know that: N + A + J = $67. We can substitute the equations from step 1 into the equations from step 2 to get: N + 4N + (N - 5) = $67. Combining like terms gets us 6N - 5 = $67. So, N = ($67 + 5) / 6 = $12. Substituting $12 back into the equation J = 4 N, we find John has 4 x 12 = $48. The answer is 48.
[Question]Giselle had 20 female doves in a birdhouse. After a month, the doves laid 3 eggs each. If 3/4 of the eggs hatched, calculate the total number of doves Giselle has now.
[Answer]
If Giselle had 20 doves that laid 3 eggs each, the total number of eggs in the birdhouse is 20 * 3 = 60 eggs. If 3 / 4 of the eggs hatched into birds, their total number is 3 / 4 * 60 = 45. In the birdhouse, there are 20 initial doves + 45 new squabs = 65 birds. The answer is 65.
