The revenue from selling x necklaces is f(x) = 10x.
the cost of buying x necklaces is c(x) = 4x + 15.
the profit from selling x necklaces is p(x) = (x) - (x).
write a function for p(x), the profit from selling x necklaces.
o a. p(x) = 14x - 15
o b. p(x) = 6x-15
o c. p(x) = 6x + 15
o d. p(x) = 14x+15
