To find out how many puzzles 1 student would complete, divide the total number of puzzles by the number of students:
80 puzzles / 15 students = 5.3 puzzles
Therefore, 1 student would complete approximately 5.3 puzzles. So the correct answer is 5.3.
Landscape Elementary uses 14 reams of paper every 3 weeks. How many reams of paper do they use each week? Round the answer to the nearest hundredth.(1 point)
To find out how many reams of paper Landscape Elementary uses each week, divide the total number of reams used in 3 weeks by 3:
14 reams / 3 weeks = 4.67 reams
Therefore, Landscape Elementary uses approximately 4.67 reams of paper each week. So the correct answer is 4.67.

To find out how much butter Jennie needs, we can set up a proportion. Since the recipe calls for 3 tablespoons of kernels and 12 cups of butter, we can set it up as:
3 tablespoons / 12 cups = 10 tablespoons / x cups
Cross-multiplying:
3x = 12 * 10
3x = 120
Dividing both sides by 3:
x = 120 / 3 = 40
Therefore, Jennie needs approximately 40 cups of butter. Hence, the correct answer is 40.

To find out how much butter Jennie needs, we need to scale the amount of butter in the recipe based on the amount of kernels she is using.
The recipe calls for 3 tablespoons of kernels and 1/2 cup of butter. Since she is using 10 tablespoons of kernels, we can set it up as:
3 tablespoons / 1/2 cup = 10 tablespoons / x cups
To solve for x, we can cross-multiply:
3 * x = 10 * (1/2)
3x = 5
Dividing both sides by 3:
x = 5/3 ≈ 1.67
Therefore, Jennie needs approximately 1.67 cups of butter. So the correct answer is 1.67.
The movie theater sold 345 tickets to a show. If 2/3 of the tickets sold were adult tickets, which cost $13.95 each, how much money did the theater make from the sale of children’s tickets if they cost 2/3 of the amount of adult tickets? Answer with a dollar amount rounded to the nearest hundredth, placing commas in appropriate places.(1 point)

To find out how much money the theater made from the sale of children's tickets, we need to calculate the number of adult tickets and the number of children's tickets sold.
If 2/3 of the tickets sold were adult tickets, then 1/3 of the tickets sold were children's tickets. We can calculate the number of children's tickets sold by multiplying the total number of tickets sold by 1/3:
345 tickets * 1/3 = 115 tickets
Since children's tickets cost 2/3 of the amount of adult tickets, we can calculate the price of a children's ticket by multiplying the price of an adult ticket by 2/3:
$13.95 * 2/3 ≈ $9.30
Now, to find out how much money the theater made from the sale of children's tickets, we can multiply the number of children's tickets sold by the price of each ticket:
115 tickets * $9.30 = $1,069.50
Therefore, the theater made approximately $1,069.50 from the sale of children's tickets.
