Answer 2

- Write and simplify a function P that represents the profit made from selling x bracelets.

in general, profit = (revenue) - (cost)

so all you have to do is subtract your revenue R(x) function minus your cost C(x) function

- How many bracelets must the company sell to break even?

the break-even point is the point where profit = 0

simply set your profit function from the first part, equal to 0, and solve for x
