Since, the fundraiser only have three prices for books($2, $5 and $10), the number of $5 book that was sold is 12.
<h3>How to form equation and solve ?</h3>
The fundraiser only have 3 prices for books which are $2, $5 and $10.
There were 6 more $5 books sold than $10 books sold.
Let
x = number of $10 book sold
Therefore,
number of $5 books sold = x + 6
There are 8 more $2 book sold than $10 book sold. Therefore,
number of $2 books sold = x + 8
A total of $250 was raised.
Therefore, the total amount sold forms the following equation:
10x + 5(x + 6) + 2(x + 8) = 250
10x + 5x + 30 + 2x + 16 = 250
17x = 250 - 30 - 16
17x = 204
x = 204 / 17
x = 12

All we have to do is use the slope formula they gave us, and <u>plug in values! </u>
<u />
y2- y1
x2 - x1
8 - 2 = 6
2 - 1 = 1
So our slope is 6/1 or just 6!
Answer:
A table of values is not going to be a function if two y values have the same x value.
If you run a vertical line through the x and get 2 y values, you are not dealing with a function. The one that does that is D. You have 3 and the two y values for x = 3. Those two y values are -4 and 0.
