Q: Daisy and Rose were enjoying their backyard pool with their dogs. If there are 24 legs/paws in the pool, how many dogs do Daisy and Rose have?
A: Daisy and Rose each have 2 legs so between them, they have 2 * 2 = 4 legs. There are 24 legs in the pool and 4 belong to Daisy and Rose so there are 24 - 4 = 20 legs in the pool. Dogs have 4 legs and there are 20 legs in the pool so there are 20 / 4 = 5 dogs in the pool. The answer is 5.
Question: Hannah's family has ten pigs on their farm. They also have three fewer than twice as many cows as pigs and six more goats than cows. How many animals do they have on their farm?

[Question]A country used to have a tax rate of 20%. They raised it to 30%. In that same time frame, John went from making 1,000,000 a year to 1,500,000 a year. How much more does he pay in taxes now compared to then?
[Answer]At 20% he paid .2 * 1000000 = $200,000. Now he pays 1500000 * .3 = $450,000. So he pays an extra 450000 - 200000 = $250000. The answer is 250000.
[Question]Jenna is adding black dots to a bunch of white blouses. Each blouse gets 20 dots, and each dot takes 10 ml of black dye. How many 400-ml bottles of dye does Jenna need to buy to dye 100 blouses?
[Answer]
First find the amount of dye each blouse takes: 20 dots / blouse * 10 ml / dot = 200 ml / blouse. Then multiply the dye used per blouse by the number of blouses to find the total amount of dye used: 200 ml / blouse * 100 blouses = 20000 ml. Then divide the amount of dye needed by the amount of dye per bottle to find the number of bottles needed: 20000 ml / 400 ml / bottle = 50 bottles. The answer is 50.
