James needs to get a new pair of glasses. His frames cost $200 and the lenses cost $500. Insurance will cover 80% of the cost of lenses and he has a $50 off coupon for frames. How much does everything cost? Let's be accurate as possible.

He gets 500 * .8 = $400 off the cost of lenses. That means the lenses cost 500 - 400 = $100. The frames cost 200 - 50 = $150. So he pays 100 + 150 = $250.
The answer: 250.
