A business owner is trying to determine the break-even point. The owner uses the revenue function R⁡(x)=−0.014⁢x^2+7,000⁢x , and the cost function is C⁡(x)=180,000+2,000⁢x In both functions, x represents the number of units sold. How many units does the owner need to sell to break even? Round to the nearest whole number if necessary.
