[Question]Julie wants to give her favorite cousin a $2345 mountain bike for his birthday. So far, she has saved $1500. Since the birthday is still a few weeks away, Julie has time to save even more. She plans on mowing 20 lawns, delivering 600 newspapers, and walking 24 of her neighbors’ dogs. She is paid $20 for each lawn, 40 cents per newspaper, and $15 per dog. After purchasing the bike, how much money will Julie have left?
[Answer]Mowing lawns will earn Julie 20 * 20 = 400 dollars. Her earnings, in dollars, from delivering newspapers will be 600 * 40 / 100 = 240 dollars. After walking 24 of her neighbor’s dogs, she will earn 24 * 15 = 360 dollars. She will therefore earn a total of 400 + 240 + 360 = 1000 dollars. Combining earnings from her job with her savings will give Julie 1000 + 1500 = 2500 dollars. Subtracting the cost of the mountain bike from the total will leave Julie with a balance of 2500 - 2345 = 155 dollars. The answer is 155.

[Question]The school is having a book-a-thon. The winning class gets a pizza party. The fifth grade has 20 students and one week to read as much as possible. The 6th grade already finished and read a total of 299 hours. How many hours does each student in 5th grade need to average per day to beat them by 1?
[Answer]The class needs to read 300 hours in a week because 299 + 1 = 300. The class needs to read 60 hours a day because 300 / 5 = 60. Each student needs to read 3 hours a day because 60 / 20 = 3. The answer is 3.

[Question]The total age of the people in Kaydence's family is 200. If Kaydence's father is 60 years old, Kaydence's mother 2 years younger than Kaydence's father, Kaydence's brother 1/2 the age of Kaydence's father, and Kaydence's sister 40 years old, how old is Kaydence?
[Answer]If Kaydence's father is 60 years old, her mother is 60 - 2 = 58 years old. The total age of the mother and father is 60 + 58 = 118 years. Kaydence's brother is half the father's age, which is 1 / 2 * 60 = 30 years. The total age of Kaydence's father, mother, and brother is 30 + 118 = 148 years. If you add Kaydence's sister's age to the total age of the father, mother, and brother, you get 148 + 40 = 188 years. If everyone's age in the family is 200, then Kaydence's age is 200 - 188 = 12 years old. The answer is 12.

[Question]Mr. Roberts can buy a television for $400 cash or $120 down payment and $30 a month for 12 months. How much can he save by paying cash?
[Answer]
Mr. Roberts will make a total payment of $30 x 12 = $360 for 12 months. Thus, the television costs $360 + $120 = $480 when not paid in cash. Therefore, Mr. Roberts can save $480 - $400 = $80 by paying cash. The answer is 80.
