Answer:4:1
Step-by-step explanation: you have to find the unit rate ( how much for 1) so you set 3 to equal 1 and to do that you divide by three so you do that to the 12 also

First we see the cost of making 200 cookies:
(200) * (1.50) = 300 $
Then, we see the amount of cookies that are not broken:
(200) * (0.30) = 60
200-60 = 140
Arley wants to 50% markup on cost and produces 200 cookies:
(300) * (1.50) = 450 $
Arley can sell the broken cookies for $ 1.40 each:
(1.40) * (60) = $ 84
For each unbroken cookie the price will be then:
(450-84) / (140) = 2.61 $
Answer:
Arley should charge $ 2.61 for each unbroken cookie
Answer:
40
Step-by-step explanation:
To solve this, we can create an equation that represents this situation. Since Christopher score 7 more than twice what Mathew scored, the equation will be:
C = 2M + 7
(Variables are representative of the first letter of each name)
Seeing as Christopher scored 87, we can put that into the equation and solve for M.
So, the equation will be:
87 = 2M + 7
Subtract 7 from both sides in order to isolate variable M on the right side.
80 = 2M
Now solve for M, which is 40 (divide both sides by 2).
Answer:
(C)Stefano should have divided by 6 when finding the mean absolute deviation.
Step-by-step explanation:
Step 1: Find the mean.
Step 2: Find each absolute deviation.
10, 18, 10, 18, 2, 2
Step 3: Find the mean absolute deviation.
However, there are 6 values in the data. Stefano should have divided by 6 when finding the mean absolute deviation.
The correct mean absolute deviation is therefore:
