One could analyze sources that were created by experts. In this case, you should look for a source that shares the same main argument, which is that people should pay for things that they own. People with credentials are credible (for the most part), and can be trusted. If experts have the same ideas and opinions in their respective fields, your thesis can be verified.

Answer:
90 miles
Step-by-step explanation:
Let d represent the distance to Grandma's house.
The speed going was ...
speed = distance/time
speed = d/2
The speed coming home was ...
speed = d/2.25
The difference of these speeds is 5 miles per hour:
d/2 -d/2.25 = 5
2.25d -2d = 5(4.50) . . . . . multiply by 4.50
0.25d = 22.5 . . . . . . . . . . .simplify
d = 90 . . . . . . . . . . . . . . . . multiply by 4
Grandma's house is 90 miles away.
Given that total amount of metal in the beginning = 8.2 square feet
Given that used amount of metal = 2.1 square feet
Then remaining amount of metal = (8.2-2.1) = 6.1 square feet
Now it says that "$183 worth of sheet metal remaining".
That means cost of 6.1 square feet is $183.
Let cost of 1 square feet of the metal = x
Then cost of 6.1 square feet of the metal = 6.1x
Both expressions 6.1x and $183 represent the cost of the remaining metal so the required equation will be:
6.1x=183
Now we can solve it to find the solution
x=183/6.1
x=30
So the cost per square feet of the metal = $30
Hence final answer is $30 per square feet.
