A company makes and sells charm bracelets. The cost of producing x bracelets is represented by the function C(x) = 180 + 8x. The revenue earned from selling x bracelets is represented by the function R(x) = 20x.
Write and simplify a function P that represents the profit made from selling x bracelets.
How many bracelets must the company sell to break even?

If this is your question: the profit function P is revenue - cost, so subtract the R - C functions and simplify to get P

At the break even point, P = 0 so set P = 0 and solve for x
