In a field of 500 clovers, 20% have four leaves and one quarter of these are purple clovers. Assuming these proportions are exactly correct, how many clovers in the field are both purple and four-leaved?
Let's think: There are 500 / 5 = 100 four leaf clovers. There are 100 / 4 = 25 purple four leaf clovers.. The answer is: 25.

A shipping boat's crew consisted of 17 sailors, with five inexperienced sailors. Each experienced sailor was paid 1/5 times more than the inexperienced sailors. If the inexperienced sailors were paid $10 per hour for a 60-hour workweek, calculate the total combined monthly earnings of the experienced sailors.
Let's think: If the experienced sailors received 1 / 5 times more money than the inexperienced sailors, they were paid 1 / 5 * 10 = $2 more. The total hourly earnings for the experienced sailors each is $10 + $2 = $12. In a 60 - hour workweek, an experienced sailor is paid 60 * $12 = $720. In a month, an experienced sailor is paid 4 * $720 = $2880. If there were five inexperienced sailors, the total number of experienced sailors was 17 - 5 = 12. If each experienced sailor was paid $2280 per month, the total combined monthly earnings for the experienced is 12 * 2880 = $34560.. The answer is: 34560.

Three cats sat on a fence, meowing at the moon. The first cat meowed 3 times per minute. The second cat meowed twice as frequently as the first cat. And the third cat meowed at one-third the frequency of the second cat. What is the combined total number of meows the three cats make in 5 minutes?
Let's think: The second cat meowed twice as frequently as the three meows per minute from the first cat, for a total of 2 * 3 = 6 meows per minute. The third cat meowed at one - third the frequency of the second cat, for a total of 6 / 3 = 2 meows per minute. Thus, combined, the three cats meow 3 + 6 + 2 = 11 times per minute. In five minutes, the three cats meow 5 * 11 = 55 times.. The answer is: 55.

Jimmy’s shorts cost 3 x $15 = $45. Irene’s shirts cost 5 x $17 = $85. Total cost for the clothes is $45 + $85 = $130. 10% discount on the clothes is $130 x 10% = $13. They give the cashier $130 - $13 = $117.. The answer is: 117.
