<h3>Write an equation that will match the story problem</h3>

<em><u>Solution:</u></em>
Given that,
David goes into a candy store with $5.00
Total amount with David = $ 5
He buys 9 peppermints for $0.15 each
And some sour candies. each sour candy costs $0.25
The equation is:
Let the number of sour candies bought be "x"
Then,
Remaining amount after buying pepper mint = 
Each sour candy cost $0.25
<em><u>Now the number of sour candies bought is:</u></em>

x = 14.6
Thus david can buy 14 sour candies
<em><u>Thus the equation that will match the story problem is:</u></em>

Where, "x" means number of sour candies bought
Given:
The three points are (-7,134), (-3,10) and (5,50).
To find:
The equation of parabola using quadratic regression.
Solution:
The general equation of quadratic regression is
...(i)
The three points are (-7,134), (-3,10) and (5,50).
Using the graphing calculator, we get a=3, b=-1 and c=-20. Putting these values in (i), we get


Therefore, the equation of parabola is
and the missing values in the given equation are 3, -1 and -20.
Answer is c
61.25 divided by 12.25 is 5
So she has enough for 5 bouquets
Multiply 6x5= 30, 30 + 4 = 34
Then 7x5= 35, 35 + 4 = 39
34+39 = 73
73/5 = 14.6 or 14 3/5
