Q: The ratio of boys to girls in a classroom is 3:5. If there are 4 more girls than boys, how many students are in the classroom?
A: Since the ratio of boys to girls is 3:5, then the class is divided into 3 + 5 = 8 parts. The girls have 5 - 3 = 2 parts more than the boys. Since 2 parts are equal to 4, then 1 part is equal to 4 / 2 = 2 students. Hence, there are 8 parts x 2 = 16 students. The answer is 16.

[Question]Nicholas bought six times as much fabric as Kenneth. If Kenneth paid $40 for an oz of fabric and bought 700oz, calculate the amount of money that Nicholas paid more than Kenneth for the fabric he bought.
[Answer]If Kenneth bought 700oz of fabric at $40 per oz, he spent a total of 700 * 40 = $28000. Nicholas bought six times as much fabric as Kenneth, meaning Nicholas bought 6 * 700 = 4200oz of fabric. If an oz of fabric is sold at $40, Nicholas paid 4200 * $40 = $168000 for the 4200oz of fabric. The amount of money that Nicholas paid more than Kenneth for the fabric he bought is $168000 - 28000 = $140000. The answer is 140000.

Question: Aliyah has 10 more phones than her sister Vivienne. If Vivienne has 40 phones, and the two sisters sell their phones at $400 each, calculate the total amount of money they have together?
Answer: The total amount of money that Vivienne gets from selling her phones is 40 * 400 = 16000. Since Aliyah has 10 more phones than Vivienne, she has 40 + 10 = 50 phones. When she sells her phones, Aliyah receives 50 * $400 = $20000. Together they have $20000 + $16000 = $36000. The answer is 36000.
Q: Christian is twice as old as Brian. In eight more years, Brian will be 40 years old. How old will Christian be in eight years?
A:
If in eight years Brian will be 40 years old, he is currently 40 - 8 = 32 years old. Since Christian is twice as old as Brian, he is 2 * 32 = 64 years old. In 8 years, Christian will be 64 + 8 = 72 years old. The answer is 72.
