David has $520 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax. He buys a new bicycle for $303.93.
He buys 4 bicycle reflectors for $10.99 each and a pair of bike gloves for $25.25.
He plans to spend some or all of the money he has left to buy new biking outfits for $73.43 each.

Write and solve an inequality which can be used to determine x, the number of outfits David can purchase while staying within his budget.

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.
