Answer:
Step-by-step explanation:
Step 1: Calculate the error (subtract one value from the other) ignore any minus sign.
Step 2: Divide the error by the exact value (we get a decimal number)
Step 3: Convert that to a percentage (by multiplying by 100 and adding a "%" sign)
1/6 because the only way the sum can be less than 4 if the first die is a 2 is if the second die is a 1.
7x - 2x - 10 = 25x + 45
5x - 10 = 25x + 45
5x - 25x = 45 + 10
- 20x = 55
x = -55/20 = -11/4
Answer:
The cost of producing the article is -3500 (Negative cost)
Step-by-step explanation:
The given parameters are
The ratio of the profit to material cost to production labor = 5:7:13
The amount of the material cost = 840 + Labor cost
Let the total cost = X
Therefore, we have;
The fraction of the total cost that is material cost = 7/(5 + 7 + 13) = 7/25
Therefore, the material cost = 7/25 × X
The fraction of the total cost that is labor cost = 13/(5 + 7 + 13) = 13/25
Therefore, the labor cost = 13/25 × X
However, the amount of the material cost = 840 + Labor cost, which gives;
7/25 × X = 13/25 × X + 840
7/25 × X - 13/25 × X = 840
-6/25 × X= 840
X = 840/(-6/25) = 840×(-25/6) = -3500
The cost of producing the article = -3500.
