Step-by-step reasoning process: Joan has (180 / 3) * 2 = 120 white socks. The number of blue socks Joan has is 180 - 120 = 60.

The answer is 60

Step-by-step reasoning process: The hay previously cost $15 per bale so 10 bales would cost $15 * 10 = $150. Double 10 bales is 10 * 2 = 20 bales. Better quality hay cost $18 per bale so 20 bales would cost $18 * 20 = $360. Farmer Brown would need $360 - $150 = $210 more.
[Q & A] The question is Chester must deliver ten bales of hay to Farmer Brown. Farmer Brown wants Chester to supply better quality hay and double the delivery of bales of hay. If the previous hay cost $15 per bale, and the better quality one cost $18 per bale, how much more money will Farmer Brown need to meet his own new requirements?
The answer is 210

Step-by-step reasoning process: One jar had 80 and the second jar had twice that amount so 2 * 80 = 160 marbles. The third jar had 1 / 4 of the first jar's 80 marbles so it had .25 * 80 = 20 marbles. When you add up all the jars, she had 80 + 160 + 20 = 260 marbles.
[Q & A] The question is Courtney liked to collect marbles. She kept them in mason jars. One jar had 80 marbles. Her second jar had twice that amount. She just started her third jar which currently has 1/4 the amount of her first jar. How many marbles does she have in total?

Step-by-step reasoning process: On the first day, the soup reduces down to 80 / 2 = 40 kg. On the second day, it reduces down to 40 / 2 = 20 kg. On the third day, it is reduced to 20 / 2 = 10 kg. And on the fourth day, it is finally down to 10 / 2 = 5 kg.
