Question 25423: In a certain mill the cost C is thousands of dollars of producing x tons of steel is given by C = 0.3x + 3.5. The revenue R in thousands of dollars from selling x tons if given by R = 0.5x. Find the point at which R=C (the break-even point).

To find the break-even point, set R = C and solve for x.

Simplify and solve for x. Subtract 0.3x from both sides.
Divide both sides by 0.2

Break-even point is 17.5 tons.
