Answer this question:Kiki likes to spend her money on hats and scarves. When she buys twice as many hats as scarves, she spends 60% of her money on hats and the rest on scarves. If she currently has $90, how many scarves will she buy if they are sold at $2 each?
Kiki spends 60 / 100 * $90 = $54 of her money on hats. The amount she spends on buying scarves is $90 - $54 = $36. If each scarf is sold at $2, Kiki will buy $36 / $2 = 18 scarves.
The answer is 18.

Answer this question:Henry went to the beach and picked up 17 perfect shells and 52 broken shells. Out of those 52 broken shells, half of them were spiral. Out of the 17 perfect shells, 12 of them were not spiral. How many more broken spiral shells were there than perfect spiral shells?
52 broken shells / 2 = 26 broken shells were spiral. 17 perfect shells - 12 not spiral perfect shells = 5 perfect shells were spiral. There were 26 - 5 = 21 more broken spiral shells than perfect spiral shells.
The answer is 21.

Answer this question:Mr. Maximilian is a dairy animal farmer and has 140 cows on his farm. Forty percent of the cows on his farm have a red spot, 25 percent of the cows without a red spot have a blue spot and the remaining cows do not have any spot. How many cows on the farm have no spot?
If Mr. Maximilian has 140 cows and 40% of them have red spots, then 40 / 100 * 140 = 56 cows have red spots. The number of cows with no red spot is 140 - 56 = 84 cows. Out of the 84 cows without a red spot, 25% of them have a blue spot, a total of 25 / 100 * 84 = 21 cows. The number of cows without any spot is 84 - 21 = 63 animals.
The answer is 63.

Answer this question:Ian spent half the money he made on doing online surveys. If he worked 8 hours doing surveys and on average he's able to earn $18 per hour doing surveys, how much money does he have left?
Ian is able to earn $18 per hour doing surveys. If he worked 8 hours doing surveys, then he earned $18 * 8 = $144. If he spent half of what he earned, then he spent $144 * 50% = $72. If Ian spent $72 of his earnings, then he has $144 - $72 = $72 left.
The answer is 72.
