<h3>
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
The electric power of microwave is 900 watts.
Step-by-step explanation:
Given,
Voltage in the circuit = 120 volts
Current in the circuit = 7.5 amp
Electric power of microwave = Voltage*Current
Electric power of microwave = 
Electric power of microwave = 900 watts
Therefore,
The electric power of microwave is 900 watts.
