Answer:
If using a calculator, you can calculate one number as a percentage of another by dividing the numbers and multiplying by 100.
Step-by-step explanation:
58300 - 8300 - 12750 - 22400 = 14850
We take the total profit (58300) and subtract the value of all 3 contracts to see what is left over. That remaining amount (14850) is the final contract.

Answer: Profit = 6.40 dollars</h3>
======================================================
Explanation:
Plug x = 80 into the equation to get
y = 0.12x
y = 0.12*80
y = 9.60
This means the store paid $9.60 for the rope. This amount of money is leaving the store owner's wallet or bank account. We'll keep this in mind for later.
-------------------
The graph shows the equation y = 0.20x
Note how the point (1, 0.20) is on the line to help see the slope right away. This trick only works when the line goes through the origin.
You could also use the slope formula to get this. The y intercept is 0 since the line goes through the origin.
This equation and graph show that the price per foot is $0.20, or it's 20 cents per foot.
Plug in x = 80 to find how much the store will make in revenue
y = 0.20x
y = 0.20*80
y = 16
The store makes $16 in revenue when it sells 80 ft of rope.
----------------------
The cost to the store was $9.60 found in the first section. The revenue was $16 found in section 2.
So,
profit = revenue - cost
profit = 16 - 9.60
profit = 6.40 dollars
You can multiply 6x5 and 6x4 then add the products, or you could simplify it by adding the numbers in parentheses and multiplying it by 6 to which you would get the same result. Remember PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
