The cost C to produce X skateboards is c=168+21x.The skateboards ar sold wholesale for $27 each,so revenue R is given by R=27x. Find how many skateboards the manufacturer needs to produce and sell to break even. (Hint: set the cost expression equal to the revenue expression and solve for x.)

Solve for x:
21x+168 = 27x

Subtract 27 x+168 from both sides:
-6 x = -168

Divide both sides by -6:
Answer: | x = 28
