Answer:
On the sale of garage One family made $1154 and Second family made $486
Step-by-step explanation:
Given:
Two families have a garage sale together the entire garage sale brought in $1640
Total Cost = $1640
Let the Second made be x
Also given one family made $182 more than twice as much of the second family
One family made = 
Now Total cost is equal to sum of One family and Second family.
Hence framing in equation form we get;
Now solving the equation we get;
Hence,
Second Family made on sale of garage = $486
One Family = 
Hence One Family made on sale of garage = $1154
Answer:

Answer:
Step-by-step explanation:
I believe the only way to solve this is by Heron's Formula.
Add up all the sides and divide by 2 to get the semi-perimeter:
113+100+86 = 299
299/2 = 149.5
Now fill in the rest, which looks like this:
where s is your semiperimeter value, a is the length of one side, b the length of another side, and c the length of the third side:
which simplifies to
which simplifies further to
which, on your calculator, is 4141.49 meters squared (that's rounded to the nearest hundredth).
On the face of it, [5.3%, 8.65%].
_____
If you mean that up to 8.65% may be added to the base 5.3% rate, then the total can be in the range [5.3%, 13.95%].
