[Question]: Jamie collects glass balls. He had 16 red balls and two times more blue balls. Later on, he lost 6 of the red balls, so he decided to buy some yellow balls to fill up his collection. How many yellow balls did he buy if, after all, he had 74 balls in total?
[Answer]: Jamie had two times more blue balls than red ones, so he had 2 blue / red * 16 red balls = 32 blue balls. He lost 6 red balls so he had only 16 red balls - 6 red balls = 10 red balls. In total he had 32 blue balls + 10 red balls = 42 red and blue balls. He bought 74 balls - 42 red and blue balls = 32 yellow balls.
So the answer is 32.

[Question]: A rancher has 340 head of cattle. He was about to sell them all for $204,000 when 172 of them fell sick and died. Because of the sickness, his customers lost confidence in his cattle, forcing him to lower his price by $150 per head. How much money would the devastated farmer lose if he sold the remaining cattle at the lowered price compared to the amount he would have made by selling them at the original price?
[Answer]:
The rancher would have sold his cattle for $204,000 / 340 = $600 per head. He was left with a remainder of 340 - 172 = 168 head of cattle. The lowered price is $600 - $150 = $450 per head. He would make $450 x 168 = $75,600 at the lowered price. He could have made $600 x 168 = $100,800 at the original price. He would lose $100,800 - $75,600 = $25,200.
So the answer is 25200.
