[Question]Josh built his little brother a rectangular sandbox. The perimeter of the sandbox is 30 feet and the length is twice the width. What is the width of the sandbox?
[Answer]There are four sides to a rectangle, the width is W and so the length is 2W, and we can put that in this equation: W + W + 2W + 2W = 30 feet. If we add the sides together, we get 6W = 30 feet. To find W, we divide both sides by 6, like this: 6W / 6 = 30 feet / 6, so W = 5 feet. The answer is 5.

[Question]The perimeter of a triangle is 160 cm. If two of the sides are 40 cm and 50 cm, calculate the length of the third side?
[Answer]To get the perimeter, you add all the sides o the triangles, so the first two sides add up to 40 + 50 = 90 cm. If the perimeter of the triangle is 160, the remaining side is 160 - 90 = 70 cm. The answer is 70.

[Question]Randy has some money in his piggy bank. He spends 2 dollars every time he goes to the store. He makes 4 trips to the store every month. If he had $104 dollars left in his piggy bank after a year, how much money, in dollars, did he have at first?
[Answer]Randy spends 2 * 4 = 8 dollars every month. Randy spends 8 * 12 = 96 dollars in a year. Randy had 96 + 104 = 200 dollars in his piggy bank at first. The answer is 200.

[Question]Vivian plays 10 Spotify songs every day. Her best friend Clara plays 2 fewer songs each day. If in June they didn't play any song during the weekends only, and there were 8 weekend days in June, what's the total number of songs they both listened to in that month?
[Answer]
June has 30 days, so if they didn't play any songs on weekends, then they played 30 days - 8 days = 22 days. If Vivian played 10 songs each day, the total number of songs she played for the month is 10 songs / day * 22 days = 220 songs. Clara played 2 fewer songs, which is 10 songs / day - 2 songs / day = 8 songs / day. The total number of songs played by Clara for the whole month is 8 songs / day * 22 days = 176 songs. The total played by both is 220 songs + 176 songs = 396 songs. The answer is 396.
