On the first day of the band fundraiser addie sells 12 items for a total of 40$ the candy bars are 2$ each and the half pound boxes are 10$ each. Part A: Graph the system of equations to represent the situation where x represents the number of candy bars Addie sold and y represents the number of half-pound boxes.
Part B: find the number of each item addie sold.

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
