To find out how many puzzles 1 student would complete, we need to set up a proportion using the given information:
15 students completed 80 puzzles
Let x represent the number of puzzles 1 student would complete.
So the proportion is:
15/80 = 1/x
Cross multiplying, we get:
15x = 80
x = 80/15
Dividing 80 by 15, we get:
x ≈ 5.3
Therefore, 1 student would complete approximately 5.3 puzzles.
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, we need to set up a proportion using the given information:
14 reams of paper every 3 weeks
Let x represent the number of reams of paper used per week.
So the proportion is:
14/3 = x/1
Cross multiplying, we get:
14 * 1 = 3x
14 = 3x
Dividing 14 by 3, we get:
x ≈ 4.67
Therefore, Landscape Elementary uses approximately 4.67 reams of paper each week.

To find out how much butter Jennie needs if she uses 10 tablespoons of kernels, we can set up a proportional relationship between the amount of kernels and the amount of butter:
3 tablespoons of kernels correspond to 12 cups of butter.
Let x represent the amount of butter Jennie needs for 10 tablespoons of kernels.
So the proportion is:
3/10 = 12/x
Cross multiplying, we get:
3x = 10 * 12
3x = 120
Dividing 120 by 3, we get:
x = 40
Therefore, Jennie needs 40 cups of butter if she uses 10 tablespoons of kernels. Rounding to the nearest hundredth, the answer is 40.00.

To find out the amount of butter Jennie needs for 10 tablespoons of kernels, we can set up a proportional relationship between the amount of kernels and the amount of butter:
3 tablespoons of kernels correspond to 12 cups of butter.
Let x represent the amount of butter Jennie needs for 10 tablespoons of kernels.
So the proportion is:
3/10 = 12/x
Cross multiplying, we get:
3x = 10 * 12
3x = 120
Dividing 120 by 3, we get:
x = 40
Therefore, Jennie needs 40 cups of butter if she uses 10 tablespoons of kernels. Rounding this to the nearest hundredth, we get 40.00.
Based on the given options:
1.67 is the closest rounded answer to 40.00.
Therefore, the 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 first need to determine the number of adult tickets sold and their cost.
Given that 2/3 of the tickets were adult tickets, we can find the number of adult tickets sold by multiplying the total number of tickets sold by 2/3:
AdultTickets = (2/3) * 345 = 230
Now, we can calculate the cost of 230 adult tickets by multiplying the number of adult tickets by the cost per adult ticket ($13.95):
AdultCost = 230 * 13.95 = $3,208.50
Next, we need to determine the cost of children's tickets, which are priced at 2/3 of the adult ticket price:
ChildrenCost = (2/3) * 13.95 = $9.30
Finally, we can find the total amount of money made from the sale of children's tickets by multiplying the cost per child ticket by the number of adult tickets sold:
TotalChildrenCost = ChildrenCost * AdultTickets = 9.30 * 230 = $2,139.00
Therefore, the theater made $2,139.00 from the sale of children's tickets.
