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
The given equations is: a=b+4
Given the following clues:
a=24+4 --- 28
a=32+4 --- 36
a= 40+4 --- 44
False
Because if you plot a graph to both the equation as i have attached the image.. you can see there can be multiple solution to the above system of inequalities.
It would be y=4x-3 because -11 show that it went down 11 units. So if it is going to go up 8 units, -11+8 is -3.
