Answer:
Option A The zeros are the hot dog prices that give $0.00 profit (no profit)
Option C. Zeros at 
Step-by-step explanation:
we know that
The zeros of the function are the values of x when the value of y is equal to zero
In this problem
The zeros of the function are the price of a hot dog (in dollars) when the daily profit (in hundreds of dollars) of a hot dog stand are zero
we have

Find the zeros
equate the equation to zero



square root both sides


in short, we simply divide the whole 300 by (3+7), to get in a 3:7 ratio, and then distribute accordingly.

Is this a relation: {(-2,1), (0,0), (0,1), (1,-2), (1,0), (1,3), (2,0)}? Explain why or why not.

It is a relation because any relation is simply a set of (x,y) values known as points or ordered pairs. There are no other qualifications needed to be a relation. We simply pair up any x and y value we want.
I think you meant to ask if it's a function or not. If so, then the answer is "no, it is not a function". Why not? Because the x value x = 0 produces more than one y output y = 1 and y = -2. Graph these points and you'll see them fail the vertical line test (ie its possible to draw a vertical line through more than one point on the graph). The same issue happens with (1,-2), (1,0) and (1,3) as well.
In summary:
Yes it is a relation
No it is not a function
The reasoning for each is stated above
Answer:
8550 pounds of coffee beans
Step-by-step explanation:
450 divided by 2= 225
38 times 225= 8550
55+p=105
subtract 55 from both sides
p=50
