[Question]Happy Cattle Ranch is home to 200 cows. Every year, the mother cows have enough calves that the number of cows the rancher owns rises by half the number of cows living on the ranch. If the rancher does not buy or sell any cows, how many cows will the rancher own on Happy Cattle Ranch in two years?
[Answer]In one year, the rancher will have 200 + 200 / 2 = 200 + 100 = 300 cows. In two years, the rancher will have 300 + 300 / 2 = 300 + 150 = 450 cows. The answer is 450.
Q: James runs a TV show and there are 5 main characters and 4 minor characters. He pays the minor characters $15,000 each episode. He paid the major characters three times as much. How much does he pay per episode?
A: He pays the minor characters 15000 * 4 = $60,000. The major characters each get 15000 * 3 = $45,000. So he pays the main characters 45,000 * 5 = $225,000. So in total he pays 225,000 + 60,000 = $285,000. The answer is 285000.
Question: A watermelon stand sold 46 watermelons. Seventeen customers bought one melon, three customers bought three melons, and the rest bought two melons. How many customers bought two watermelons?
Answer: The customers that bought one watermelon bought 1 * 17 = 17 melons. The customers that bought three melons bought 3 * 3 = 9 melons. The stand sold 46 - 17 - 9 = 20 melons to customers who bought 2 melons. Thus, 20 / 2 = 10 customers bought two watermelons. The answer is 10.

First find the percentage of ads that aren't interesting: 100% - 20% = 80%. Then multiply that percentage by the percentage of ads that don't get blocked to find the percentage of ads that meet both criteria: 80% * 20% = 16%. The answer is 16.
