[Question]Megan pays $16 for a shirt that costs $22 before sales. What is the amount of the discount?
[Answer]Let x be the amount of the discount. We have, 22 - x = $16. We change the writing of the equation:. 22 - x + x = 16 + x. So, 22 = 16 + x. We then Remove 16 from both sides:. 22 - 16 = 16 + x - 16. So, 22 - 16 = x. So, the amount of the discount is x = $6. The answer is 6.

[Question]Alice is planting bushes around three sides of her yard. If each side is 16 feet long, and each bush fills 4 feet, how many bushes does she need to buy?
[Answer]First find the total distance the bushes need to cover: 16 feet / side * 3 sides = 48 feet. Then divide the total distance to fill by the distance each bush fills to find the number of bushes Alice needs to buy: 48 feet / 4 feet / bush = 12 bushes. The answer is 12.

[Question]Milly and Floretta are having a water balloon fight in their garden. They use 3 packs of their own water balloons and also use 2 packs of a neighbor’s water balloons. Each pack of water balloons contains 6 balloons. Milly and Floretta fill all of the balloons then split them evenly, but Milly takes an extra 7 balloons when Floretta isn't looking. How many water balloons is Floretta left with?
[Answer]Milly and Floretta have a total of 3 packs of their own water balloons + 2 packs of the neighbor’s water balloons = 5 packs of water balloons. So there is a total of 5 packs of water balloons * 6 balloons per pack of water balloons = 30 water balloons available. As they split them evenly, they each have 30 water balloons / 2 = 15 water balloons. After Milly steals some balloons, Floretta is left with 15 – 7 = 8 water balloons. The answer is 8.

First find how many consonants are missing: 21 consonants * 1 / 7 = 3 consonants. Then add the number of missing vowels to find the total number of missing keys: 3 consonants + 2 vowels = 5 keys. The answer is 5.
