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 first, third, and fourth choices are functions. A relation is a function when x does not repeat. For the second choice, -4 repeats. Therefore, it is not a function. The other choices do not repeat an x-coordinate, so they are correct.
To find equivalent numbers you multiply the top and bottom by the same number. Examples are: 2/10 (by 2), 3/15 (by 3), 4/20 (by 4), etc.
1 * 9 = 9
------------
5 * 9 = 45
So another is 9/45
