Before washing the car Fred had $14 - $6 = $8. Fred spent half his allowance for the movies, so 2 * $8 = $16 allowance.
The answer: 16
Reverse engineering the question: Fred spent half of his allowance going to the movies. He washed the family car and earned 6 dollars. What is his weekly allowance if he ended with 14 dollars?

The club has a female group which has twice as many members as the male group, so there are 2 + 1 = 3 groups in the club. There are 18 members in the club, which means there are 18 / 3 = 6 members per group. Since the number of female members consists of two groups, then there are 6 * 2 = 12 female members in the club.
The answer: 12

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: 34560
Reverse engineering the question: 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.


Max gets 1 + 2 = 3 trains per year. He repeats this for 5 years, meaning he gets 5 * 3 = 15 trains. When this number is doubled by his parents, it becomes 15 * 2 = 30 trains. Since he already had 15 model trains, his total becomes 15 + 30 = 45 trains.
The answer: 45

Max likes to collect model trains. He asks for one for every birthday of his, and asks for two each Christmas. Max always gets the gifts he asks for, and asks for these same gifts every year for 5 years. At the end of the 5 years, his parents give him double the number of trains he already has. How many trains does Max have now?
