We have a question: Barbara Blackburn can type 212 words per minute. Due to Carpal tunnel syndrome, Barbara cannot use her left hand for a while so her typing speed is now 40 words less per minute. If she is supposed to type a document with 3440 words, how many minutes will it take her to finish typing the document?
And an answer: 20
So how you got the answer?
Due to carpal tunnel syndrome, Barbara can only type 212 - 40 = 172 words per minute. So, she will be able to finish typing the document in 3440 / 172 = 20 minutes.

We have a question: The carousel at the fair has 3 blue horses, three times that many purple horses, twice as many green horses as purple horses, and 1/6th as many gold horses as green horses. How many horses are there total?
And an answer: 33
So how you got the answer?
First find how many purple horses there are: 3 blue horses * 3 purple / 1 blue = 9 purple horses. Then double that number to find how many green horses there are: 9 purple horses * 2 green / 1 purple = 18 green horses. Then divide the number of green horses by 6 to find the number of gold horses: 18 green horses / 6 green / 1 gold = 3 gold horses. Then add the number of horses of each color to find the total number of horses: 9 horses + 18 horses + 3 horses + 3 horses = 33 horses.

We have a question: Scarlet saved $80 to spend on jewelry. She bought a pair of earrings that cost $23. Then, she bought a necklace that cost $48. How much of her savings have left?

Scarlet spent $23 + $48 = $71 for the jewelry. So, She was left with $80 - $71 = $9 on her savings.
