Which property is represented by 5+8(-8)=-8+5?indentity, associative, commutative, distributive
1 answer:
Answer:
The Commutative property is represented by 5 + (-8) = -8 + 5.
Step-by-step explanation:
We are the following the following expression below;
5 + (-8) = -8 + 5
- Identity property;
This property says that is any number is added to 0, then the result is the number itself, i.e.;
2 + 0 = 2 or (-7) + 0 = -7.
- Associative property;
Suppose there are three numbers; a, b and c.
So, this property hold the condition that; a + (b + c) = (a + b) + c
If we add the second and third numbers and then add the first number to it or if we add the first and second numbers and then add the third number to it, the result will be the same.
- Commutative property;
Suppose there are two numbers 6 and 8.
This property states that if we add 6 + 8 or 8 + 6, both are equal, i,e;
6 + 8 = 8 + 6
14 = 14.
- Distributive property;
This property states the following condition;
a (b + c) = (a
b) + (a
c)
So, 5 + (-8) = -8 + 5 is represented by the commutative property.

Answer:
It should charge $48 for a five-pound package of salmon.
Step-by-step explanation:
Assume the variable cost per package is $30, and the fixed cost is $250,000.
We know the formula: Profit = Total revenue - Total cost.
Profit = 38000
Total revenue = P x Q (P= price, Q = quantity)
Total revenue = 16000P
Total cost = [Fixed cost + (variable cost x quantity)]
Variable cost = 30
Fixed cost = 250000
Putting all values in formula: (P x Q) - [FC + (VC x Q)]
Solving for P;
=>
=>
Cancelling zeroes and dividing by 16 on both sides, we get;
P = $48
Hence, the company should charge $48 for a five pound package of salmon.
