Answer:

Step-by-step explanation:
Let the quadratic function be

We substitute
into the equation to obtain;


We substitute
to obtain;


We finally substitute
to obtain;


We put equation (2) into equation (1) to get;





We add equation (4) and (5) to get;



We put
into equation (5) to get;



The reqiured quadratic function is

2(5x)2(-7)=2x+10
2(5x)= 10x
2(-7)=-14
10x-14=2x+10
Solve:
10x-2x=8x
8x-14=10
14+10=24
8x=24
24/8=3
X=3
Answer: The number of ceral boxes per day.
Because the slope will be [rise of the grah of the model function] / [run of the graph of the model function].
rise = [increase in the number of cereal boxes sold]
run = [days elapsed ]
rise / run = number of cereal boxes sold per day
