Marcy can make 3 spears out of a sapling and 9 spears out of a log. How many spears can she make out of 6 saplings and a log? Let's be accurate as possible.
First find the total number of spears she makes from saplings: 3 spears / sapling * 6 saplings = 18 spears. Then add the number she makes from the log: 18 spears + 9 spears = 27 spears.
The answer: 27.
