Spaceship model kits originally cost d dollars online. You buy each kit on sale for 30% of the original price, plus a shipping fee of $3.50 per kit. After assembly, you sell each model online for (2.5d+5) dollars. What is your profit on each model spaceship sold?

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.
