Question

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?

Answer 1

the break-even point occurs when revenue = costs

so simply set the revenue and cost equation equal to each other, and solve for x. if your answer is a non-integer, round up to the nearest integer.
